The most worrying fact for me is their future is so unplanned as well, only the Aquaman movie seems to be going as planned.
The Flash movie hasn't yet started and WW2 is still in cast early pre-production, the Batman movie is on hold, man of Steel 2 isn't planned, but they've cast so many actors and given the release date for justice league 2 with currently only Aquaman and maybe the flash between it, that's like 0 character growth between movies just so they can throw darksied in and reportedly bring in green lantern

I've loved these movies despite their flaws, but the majority don't, so a quick replanning and making the management of the ship tighter is required from WB

Considering this had a lower than expected opening, next weekend is probably going to see a drop larger than 60%, which is actually the norm for DC films.  But, let's say it's only 60%, which would be ~$40M for the weekend.  Highly doubt it'll make $50M-$80M between now and Friday.  And considering this movie cost $300M to make, it'll need to hit $600M WW to break even.  That doesn't even include the huge marketing budget for this film.  That probably takes it to $800M to break even.  BO Mojo is predicting it will be in line with other DC movies and only have a ~2x multiplier for the rest of its run, which means only ~$200M-$220M domestic when its run is over.  That means the rest of the world needs to make ~$580M-$600M, which is more than any other DC movie.  I highly doubt that will happen.  Especially since BvS is the DC movie that made the most in the rest of the world, and that opened ~$70M higher than JL.  This movie is just stumbling on almost all accounts.

The Godfather is the safest movie in the world to mention as a "real movie". How original of Lucas-Rio.

Also, superheroes actually die a lot compared to the Rock, so that's a silly thing to say.

Look, there's a place for all types of movies and superheroes just happen to be the hot thing right now. And deservedly so, because they have been represented very poorly on film until these last few years. There's still lots of other movies coming out all the time, so just watch them instead, if these heroes are not your thing.

Besides, make mine Marvel!

This film went way over budget really due to the reshoots. Rumors say that 15-20% of the film is the Whedon part, which means most cuts removed Snyder's work. It seems that BvS still impacted JL, so the best way to go is removing Snyder from the direction. I'm not sure if it's entirely his fault, but he is too associated to these failures to keep going.

Matt Reeves said in a recent interview that Snyder will remain (he also said that Ben Affleck will remain as Batman), but I take that with a grain of salt.

I believe it's more likely that Warner keeps Joss Whedon for the JL. I've read that most of the Superman scenes on the film were either filmed by Whedon or edited to fit his vision. And that's a way better Superman than what Snyder showed on MoS and BvS: he is now hopeful and light-hearted and that's the real Superman. The whole russian family was Whedon and I thought it added a bit of heart to the end drama, with the heroes going out of their way to save them. Whedon also added all these stuff about the Flash lacking confidence during battles, which was a nice touch since he really has way less experience than the others (except Cyborg). The first post-credit scene is also Whedon and that was a big nod to comic book fans and ended up great.

You can check the rumored changes Whedon did here:

If this is all true, then Whedon really improved the film a LOT. Most of the things Snyder did that were left out were a bit crappy and the Whedon changes were key to make characters more relatable.

I watched Man of Steel and BvS in theatres, I didn't really think that they were that bad.

Please list me some superhero movies that have been good the past few years because my experience is that they peaked around early to mid 2000s.  The first couple X men movies were okay and they went downhill.  I liked the first Iron Man and the second one was almost bearable.  However the third was just terrible.  In my opinion they are just getting worse.

I'm of the opposite spectrum. Pretty much everything that was Wheden I hated.

The random Russian family? Stupid. Supid Stupid. Stepenwolf sets up base in some abandoned nuclear facility where there is no people, he is hidden, ect. It shows many scenes of the parademons, thousands of them, checking like every house windows. Yet this family goes unnoticed? If there were any people living in that nuclear fallout zone, they would have been found and killed in seconds. Remember, apparently parademons can smell fear and hone in on it in seconds. Apparantly that family was not scared at all? But then since they were there, superman and flash need to leave final battle to have a quick save two people scene. Just wasted time. Felt like in Avengers movies where you had that random chick being saved by Cap, or in Age of Ultron you had some random person focused in the saving. It just is awkward. How many minutes did we waste on the Russian family scenes that could have been used to show some more flash/cyborg backstory or more of aquaman in atlantis. Hell, go rewatch the most recent justice league trailer. There is like a full minutes worth of stuff in that trailer alone that is not in the movie.

Yes, pretty much all of superman lines were Wheden. And all of his lines were very cringeworthy. Do you bleed? Really. The world needs me, not you? Really? I wish I was dead? Really? Besides looking horrible CGI lip, they were either a cringy joke or just so so so out of character. The whole batman/superman do you bleed scene completely made that scene ruined. It went from being a Superman being resurrected that was confused/lost/instinct mode that was seemingly defending himself to all of sudden he was doing evil things. He recognized Batman and was going to kill him. Before that, it was your typical person gets resserected and isn't themselves. But at the Batman part it was superman killing batman.

The worst part of the whole movie, which pretty sure was Wheden, was the Batman/Wonder Woman romance section. The whole part where they are searching for the motherboxes/Steppenwolf and Batman goes to take off his suit to look at his bruises. WW shows up randomly wearing some red cape/scarf thing. WTF. Why did she all of a sudden throw that on? Guessing it somehow helped hide her pregnancy, but regardless it was jarring. But then we were stuck suffereing through some wheden fanboy Bruce/Diana romance. Why do all female super heroes need to be forced into a romance? I'm sure the fans of Wonder Woman movie, loved seeing her reduced to a Batman conquest.

And every batman fan should be pissed at this movie. Not only did he not really have any epic moments, such as the warehouse scene in BvS, but he also was apparently Tony Stark. He had so many freaking jokes and was completely a non batman. Tell me in what comic or even animated thing has batman ever acted as he did in this movie? The whole movie he was either cracking a joke or moping about killing superman.

Actually, Box Office Mojo was expecting an opening of $118 million.  So the film performed well below (about $20 million under) Box Office Mojo's (and the entire industry's) expectations:

'Justice League' is Coming Together for $110+ Million Opening

Looking at a #1 finish, Warner Bros. and DC Comics' Justice League will debut in 4,051 theaters with industry expectations right around $105-115 million. Given Wonder Woman debuted with $103.2 million earlier this year, Suicide Squad opened with $133.6 million last year and Batman v Superman opened with $166 million, those expectations might seem low given this is essentially DC's equivalent to Marvel's The Avengers. While that is true, the DC Extended Universe has taken something of a different path than the Marvel franchise, playing it big almost from the start by bringing Batman and Superman together and introducing Wonder Woman in Batman v Superman immediately after Man of Steel, followed that same year by the anti-hero feature Suicide Squad. As such, while these expectations appear a little low, they aren't entirely unreasonable.

Looking at IMDb page view performance, Justice League is pacing just ahead of Wonder Woman at the same point in the release cycle and well behind both Batman v Superman and Suicide Squad. And if you take the average opening for a film of this type from Warner Bros., debuting in this many theaters, you only get a ~$95 million opening. That said, based on IMDb page view performance Justice League is over-indexing, leading us to believe an opening no lower than $115 million is likely.

Not helping matters, reviews for Justice League are only marginally better than those for Batman v Superman and Suicide Squad, as it currently holds a Metacritic score of 47. There has also been a bit of controversy surrounding the suppression of the film's RottenTomatoes score, but just as previous films didn't perform entirely well with critics, their opening weekends appear critic-proof and that should be the case again here. How it plays beyond opening weekend is another matter.

All told, we're anticipating an opening around $118 million or higher for Justice League.

Spoilers below on my favorite scenes/parts of the movie.

1. The beginning montage of Superman being dead with the song Everybody's Knows playing. That scene was beautiful and really sunk in the effect of Superman being dead and somber atmosphere.

2. The flashback of the Amazon/Human/Gods/Green Lanterns/Atlanteons vs. Steppenwolf/Parademons war. That was a great scene, especially the Lantern dieing and his ring flying off to find another person.

3. The Superman resurrection until he saw Batman. Especially the part where he sees the Flash running. That was just amazing and Flash's face was epicly funny as his eyes reflected his oh shit moment.

4. Post Credit Scenes. While Supes face screwed up a perfect Flash/Superman race scene, that was still awesome. Been done like 3 times already in other media but still cool to see this iteration. Then Deathstroke and Lex scene was also beautiful. The visuals, the local, the atmosphere. The walk up the stairs to Lex. It was amazing, as well as makes one insanely hyped for future. (though with WB at helm I have no hopes for future)
