I finally watched Man of Steel today!
I REALLY enjoyed the action, because this looked like I expect a Superman fight to look like. I would even say: Best Action sequences of a superhero movie so far. Snyder knows how to make things look nice. Every single scene in this movie looks like a piece of art.
And I liked how they described Superman's childhood... how he had to learn how to deal with his powers. There were several interesting ideas in this movie and sometimes I got the feeling "this is a Nolan idea for sure". Well, maybe I'm wrong, that's just how it felt.
What I didn't like - and that's something I already knew from 300 - was the really bad dialogue. The people in Snyder's movie don't act like real people, it's all an epic show with tons of pathos and dumb lines. That's appealing in some way, but it lacks intelligence and substance.
So even if they can't hold up to this movie optically I still prefer Nolan's Batman and the Avengers / Iron Man. Nolan's Batman movies were well written and clever. And the Avengers are more fun, because they don't take themselves so seriosly. Superman just looks really good (the movie of course...
But I am looking forward to how they do the Batman crossover.
