Well, color me impressed with the trailer. You can't reproach Snyder's visuals, he really knows how to set up a piece. Batman looks great, like a Miller drawing come to life. The scene with Superman on the sky with the sun behind me looks a lot like a panel from All-Star Superman.
Since we are talking about the sequel nature of the film, I must add that in the beginning this was going to be a MOS "clean" sequel, then throwing Bats into the mix, then came the name, first billing Batman (which by the nature of the film seems accurate, because apparently is Batman who incites this battle), and then adding other JL members too. This troubles me a lot, because it seems that, at least in the beginning, they had no roadmap and they were making it as they went. However, it seems that the path has been cleared.
It gives me hope that Chris Terrio rewrote the script. Listen, I haven't seen his work but it seems like he has good credentials. Goyer is good with a lot of ideas, but the execution seems lacking. TDKT was mainly the Nolan brothers with creative input by Goyer, and that combo was great. Man of Steel showed some carelessness choices from both him and Snyder, so I was wary about this one.
Digging deeply in the story so far, the main beef I had with Man of Steel was that it was a film that talked a lot about hope, but it didn't show it. The ending was particularly abrupt and the nature of the film was somewhat grim. Sure, the scene I liked the most was Superman learning to fly, the remembrance of little Clark with the cape (even though I think the film mishandled Jonathan Kent role, paling in comparison with the original Superman film version). At the end, a single "He saved us" from the Jenny character didn't do enough.
Parting from that, it seems that in BvS context, Superman has definitely inspired people. But it seems that this inspiration is wrong headed. It is certainly an interesting interpretation, but I just hope it is a balanced belief. We see some "Hope" branded soldiers kneeling before Superman, people trying to reach to him in a sort of deifying way. Seems a analogue to the Batman Copy-Cats from TDK. It is a must for people to see Superman as a true symbol of hope, but this suggest this inspiration is corrupted.
There is a question though. What does Superman do to warrant Batman's intervention? Is it the wrong attitude of the people for Superman? Is it something that Superman does? I just hope we don't get a Miller treatment for Superman too. How much does the destruction of a third of Metropolis has to do with Batman's motivation to fight? What is Lex Luthor role in all of these? And, what purpose does the fight has? Is it to stop him? Because even in TDKReturns the intent was to make a point to the world, I wonder if this is the case.
The movie is promising a lot of complex issues, I really hope it delivers. I'll be wary optimistic for the time on.
