Not sure why people are saying this movie won't "flop"
A "flop" isn't just based around what it cost to make + what it cost to market compared to what it makes...but also what the studio projects it to make...
If it cost a total of 300 million and they make 800 million and they roughly keep half of that for 400 million...but they projected the movie to make a billion...the studio is going to consider that a flop...200 million less than what they expected..
Their entire upcoming DC movie franchise is riding on this one film...if it doesn't make what the studio thinks it should then everything outside of Ben's batman movies could be up in the air...
And that is probably the most critical part of the movie...are people going to watch this and just view it as a single batman superman movie...or are they going to watch it and then be interested in watching the rest of the DC Universe? Because it's not about getting people to see this one movie...it's about getting them to see the 8 movies behind it...
Personally I've got some serious trepidation about what they are trying to pull off...they felt they needed to add batman to a superman movie, so it doesn't seem like the studio thinks superman is a strong enough character to stand on his own...or did they feel they needed to add superman to a batman movie...because they don't feel like batman can stand on his own?
Now they stuck trying to tell a superman story...a batman origin story...a wonder woman origin story...all in the same movie...and this has to at least start leading to the formation of the Justice League...that is a lot of shyt to try and do in at most 2 and a half hours...
It is head scratching to me that they continued on with this and are releasing this first over at least one Batman reboot movie just for logic's sake...to me the batman movie is already screwed logically...it is going to be hard to show batman struggling with a real villain in his own stand alone movie when he has already gone toe to toe with at least superman and doomsday...unless it's some sort of physiological battle and while I am not the biggest Nolan fan he hit all 3 of those out of the park with Scarecrow, Joker, and Bane...gonna be nigh impossible to top that...
Also that 300 million i estimated is probably very conservative...I'd be shocked if 300 million covered the marketing cost...
But then again they dropped the ball on the Nightwing movies after Nolan tossed them a layup so...
