The Good
I think the actors they have Supes, Bat, WW, Alfred, etc. Were all fine. They look and fit the part well.
The Bad
This is the most strung together film I've seen. Just to go through the first hour or so. We start with a dream sequence of Bruce. Followed by a past memory. Followed by Lolis being saved and Superman. Followed by the Senate shit. Back to Bat. Back to another dream sequence from Bat. Introducing Lex. Lex and the Senate girl. Etc.
There is zero sense of time or pacing. Its an assembly piece without any cohesion.
Then they finally start to focus it and what is left is basically non nonsensical shit. The reason supes fight bat is Lex taking his mommy and suddenly wants to kill him for it...Batman stops because of Martha...Doomsday is created in a manner of like 2 hours... Lex summoned Darksied... to avoid the pitfall of the last film, every place is inhabited(Yes the middle of Metropolis, Port of Gotham, Island, Lex's camp), complete with announcing it to the audience each time.
And the cardinal sin of the film is that it is long on top of being boring. I sat there from about 30 minutes in wondering when this shit is over.
Was that the flash going back in time in Bruce's dream?
