The trailer was pretty impressive but I was surprised how much ground from the first movie seemed to be re-trodden. Admittedly, it could be done in flashback and might take up a small portion of the movie.
But, the new take on his POV while swinging aside, it seemed very like Raimi's first movie - more alike than say, Batman Begins and Tim Burton's first movie. Obviously, they're about the same character, so you expect a certain resemblance but I was expecting more of a contrast.
Of course, it's only a teaser trailer, so I'm not placing too much on this initial reaction.
