Guys, this is
The Dark Knight Returns.
I have to figure some money is being thrown Frank Miller's way because they are making (or stealing) his comic.
Even Affleck's batsuit is right out of the comic with the small bat ears.
The problem is that not every comic can be transferred to film. Trust me when I say that this is one of them.Even in the comic realm this is an ELSEWORLD tale. That means it never really happened in the comic reality. It's not canon.
Now it is understandable to want to make a comic featuring DC Comics two biggest stars, but they simply should have crafted an original tale, something that could lead to the eventual JLA movie that we all know is coming.
All they had to do was have Lex Luthor doing something bad in Gotham City. That's all you need for Batman and Superman to meet and work together. Instead, WB is trying to make a movie out of a comic not suited to be a major motion picture.
Throw in Affleck as Batman and you have an epic disaster on the way.
The person I feel bad for is Cavill. Man of Steel was bad. That's why they are doing this instead of giving Batman a breather for a while. They don't have faith in another solo Superman film.
