It's not bad, just horrible ( ͡° ͜ʖ ͡°).

Because people didn't go and see it? Similarly to how Miles Teller was a cynical appeal to the youth audience, casting Jordan was a cynical appeal to pander to the "progressive" crowd.

I'm shocked and/or horrored.

Whatever, Marvel getting the rights or not, nothing can be done with it for like years. They'll do their movies, and whatever, introduce Inhumans as replacements for mutants and any FF film can't be out until 2020 at the earliest.

....well, all Fox have to do is release a piece of crap film every 7-8 years and they keep the rights.

the X-Men movies, especially recently, have been pretty solid. but overall I agree with you. Fox just does not ever seem to know how to get the balance right. they either go too big or too small, too over the top or too boring/serious

for a while I thought Sony could be trusted with super hero movies as I thought they did a superb job with Spiderman 1/2 however 3 was ehh and then the "Amazing Spider-Man' reboot series has been mediocre

at this point beyond the X-Men movies and the occasional pretty decent random Warner Bros Batman movie it seems like Marvel is the only one consistent with Super-hero movies. and in reality I guess we have to thank Disney since Marvel only become its current self once it was taken over by them

DC had some pretty good movies. Also, I'm sure they're going to release more movies in the next years(can't think of them off of the top of my head though)

I don't care about DC comics at all but there have been some good movies, they're the ones who proved a dark super hero movie could work.
Also I'm sick of hearing people always wanting marvel to have ff/xmen back. They don't shit gold and half their movies suck!

Yeah, but you'd hope under a new direction, both the FF and X franchise would get better from then and on out.

People didn't go see it because it was a shit movie, not because of any particular casting choices. The movie would have been a success if it had been an actually good movie and it would still have had a black actor in a role that has historically been a white person. Michael B. Jordan's skin colour had nothing to do with this movie being a bad movie which was the sole cause of the movie flopping. So why are you trying to make out like his skin colour was a factor? Are you saying that the vast majority of potential Fantastic 4 movie watchers are sufficiently racist that they would refuse to see the movie because it has a black actor playing an historically white character? I'm pretty cynical about humanity as it is right now, but even I don't have that low an opinion of the general population.

A person's skin colour is pretty much irrelevant when it comes to any fictional role for character credibility, moreso for a character like Jonny Storm who is basically just a gung-ho, hothead, grunt. A person's age can be far more relevant to character credibility when trying to present someone as having had mature experience as a leading scientific mind. A person in their 20's who looks a bit like a Jock and a teen hearthrob (I don't see it in Teller myself, but then again I'm not a teen) just has a hard time being seen as a credible leader in the scientific community. You can have an age approprioate heart throb (Brad Pitt, for instance) play a science genius, or you can have a young person who actually looks like a science genius. But you can't have a young heart throb. Jesse Eisenberg would have been a better choice for a young looking science genius. But even so, as miscast as I think Miles Teller was, his casting into the role of Mr Fantastic was not the reason the movie was a flop. 

I bet you wouldn't say the same thing if a character was changed to white.

Fanboys moan because of treatment outside of the MCU and FF and X-men's establishment in the MU/616 as a whole. FF were the first Marvel superhero team, they are the Marvel family. Mutants are the definition of persecution in Marvel world and hold huge sway over many things, there are numerous mutant characters in the Avengers line ups and history that would fit amazingly into the MCU. The fact that FF current'y don't have a monthly book and Mutants/X-men are being drowned out for the Inhumans is grating on fans minds and many want Marvel to have the rights back so that they stop abusing these characters.

It's true, half the FF/X-men movies do suck but remember, not all of the new MCU films are masterpieces. I didn't think much of Ironman 2, Cap A 1 or Thor 2 myself.

In my personal view, no mutants, no Marvel. Many people don't seem to know how much influence and the idea of mutants really have on the MU and it's nothing to ignore.
