I'm conflicted. I like a lot of Snyder's imagery, but some of the scenes they show are borderline baffling. Hopefully they better suit the character and the story when seen in context.
So... cautiously optimistic?
I think there are only two options with this movie - it will be either a knockout or a complete failure in both tone and execution. I am very curious to see how it ends up and whether Snyder can make this more than nice to look at. Visually it will be stunning - there is no doubt about that. What worries me is the quality of the screenplay and the characters and how they translate to the screen.
The Dark Knight Rises was a huge letdown for me, let's see if Nolan can do better as a producer here. The combination with Snyder as director is very intriguing. The question is, will this work? But I do love the tone and the camera work they are showing here. It has a certain atmosphere that will be very interesting to see if they can maintain through out the whole movie.
TDKR was such a mess, I'm actually amazed that Nolan was capable of producing something so inferior - to any of his films. It's his worst movie IMO and I believe repeated viewings will only accentuate that over time. The film has so many problems, plot holes, inconsistencies... Argh, I better not start with that, cause I only get frustrated thinking about it...
The problem that I see with Man of Steel is simple - Superman is not Batman. You can't apply the same techniques that you used to tell a Batman story to tell the one about Superman. They are cardinally different characters and you have to approach them that way. Take The Avengers for example - it's a completely different take than Nolan used for Batman. But in the context of the story they were telling it worked wonderfully. I do hope that they find the right angle for Superman. It all lies on the shoulders of Snyder. I think this will be a tipping point in his career - he has the chance to really prove himself here as a director. I really hope he succeeds. As Rene said, I'm cautiously optimistic.
