But it's projected to go all the way to 900 million dollars according to OP and it's still a flop. EVEN if I admit that this movie costs 450 million dollars which is absolutely insane (if I were in charge I'd fire IMMEDIATELY the guy in charge of finance and spending), even admitting this, with 900 millions you still make money even with a very badly managed budget and a total price tag of 450 million dollars to make the movie.

It's not getting to 900M LOL. Are you not paying attention to anything in real time?

Weird, because I looked at the poster and thought "Dope, I loved that book!" and then immediately swore the movie off after watching the trailer. It may not have been very good, either, but the very blatant identity politics they injected into one of my favorite books chased me away long before the reviews did.

It is a flop.  A movie flops when it fails to earn back its budget plus marketing budget.  This movie will fail to make back even its production budget. 

Corporations are more hooked on money than junkies on crack. The movie made something like 350 million dollars if I'm not mistaken and they call that a flop. It's gotten to the point that if a movie doesn't make more than a billion dollars it's a flop.

This movie is less successful than the others in the franchise granted but calling it a flop when it made 350 million dollars. Has the dollar depreciated so much that 350 millions is nothing?

Solo needed to make $500M at the box office (theaters keep ~50% of the earning from a film) to just break even on the $250M production budget.  You add in an estimated $100M advertising budget and this film needed to make ~$700M just to break even.  This film will not even cross $400M WW.  So, in the end, Solo lost Disney ~$160M.  That is a flop.

It's the same reason TLJ is seen as a big disappointment.  You look at $1.33B and that looks great.  However, things have to be taken into consideration.  Disney only sees half of that money, which means they got ~$666M (hmm) of the grosses for that film.  Given that that film most likely had the same $250M budget, plus probably ~$150M in promotion, they made ~$266M off of it.  That might seem nice, but when you compare it TFA, its a poor result.  That films grossed $2.07B, of which Disney got ~$1.03B.  Given that it probably had a similar budget to TLJ, they made ~$630M off of it.  Enough to pay for TLJ and Solo's production budget, plus an advertising campaign.  It doesn't help that TLJ was predicted to make ~$1.8B WW, and its opening weekend seemed to enforce that estimate.  Then, the 68% drop the 2nd weekend happened. 

TLJ also had the dishonor of dividing fans, which caused many of them to just give up on the franchise.  This meant not only do they have smaller ticket sales for future installments, but much lower merch sales, where SW makes a lot of its money from.

Again it bombed because it was bad, not because the identity politics they injected into it.  Blaming a movie bombed because of SJW or injection of identity politics is almost Alex Jones level of insanity.  Also the movie was directed by a African American female so if the cast would have been completely white like in the book that actually would have been weird.
