Man of Steel was a fantastic movie, and so was Watchmen. He is one the most skilled directors around in terms of tech and style and all the flack he gets, he is getting because of the type of product he is selling.
All he had to do was to drop the slow-mo. What's left now is prime photography and dynamic action sequences that aren't trying to confuse you with shaky-cams and close-up shots. Only the Russos outdo him and outclass him in terms of quality of action sequences. If those dumb-asses at Warner had left the warehouse sequence where it was, inside the movie instead of making it into a commercial, right now they would have the same amount of people gashing over it with the enthusiasm people reserve to the Cap vs Bucky action in Winter soldier.
Snyder was doing fine until WB decided to pull a Batman v Superman and fuse two inconsistent movies into a disastrous mess.
The actual idea behind Batman v Superman was really ingenuous. First it was perfectly fitting the heritage of Nolan's Batman, since in the movie Bruce goes through what people in Gotham went through once he appeared the first time. As Joker said "he changed things". He is finding himself at the other side of the equation: there's someone who is more powerful than he is, as a symbol and as a hero, and of course he starts getting nightmares of all sorts including the very one where he felt his helplessness for the first time.
Second, the idea that some people would have a fucking psychotic attack at the undeniable proof that God really exists or that aliens really exist, doesn't look that ludicrous to me. Actually, now that Trump won the election a character like Lex Luthor doesn't seem that far-fetched to begin with. The real problem with Luthor wasn't Eisenberg or the sudden introduction of mystical intervention into his actions, it was the fact that it's never really explained why he lost his mind at the idea of God not only being real but also being "all-good". The screenplay should have treated Superman as a side-character, making us see him through the eyes of Bruce and Lex, all the while focusing on deeper introspection of Bruce and Lex's motives. But, hey, IT WOULD HAVE BEEN TOO DARK, right?
This was a BATMAN MOVIE, but since they made people wait for four years and since WB wanted to turn the whole thing into a cash-cow, they worked on this project as if it was a pilot for a tv-show. And they fucked it up.
I refuse to believe that garbage like Dark Knight Rises, or at least everything in Dark Knight Rises after the first Bane fight, or Batman v Superman are Nolan and Snyder responsibility.
