I like it. It’s tasty. It makes me want to dig out my copy of the first film’s soundtrack and play it right now. And FWIW, the opening shots are reminiscent of that bit in Batman Begins, which itself was taken from the Batman comics, where the young Bruce Wayne falls into a well and discovers the cave under Wayne Manor.
UPDATE: Whoops, turns out that was a fan made teaser. And I guess it shows how out-of-it I am, when it comes to movie-promo stuff, that I didn’t recognize any of the footage it used.
