The trailer is definitely awesome, but these days trailers are theatrical productions in themselves (like music videos). It's entirely possible that ALL the decent scenes in a 2 1/2 hour movie be squeezed into a 45 second trailer, as long as they are a ) put in out of sequence; b ) made to flash across the screen in quasi-subliminal fashion; and c ) accompanied by suitable mood music. Case in point? The Dungeons and Dragons movie (the WORST movie I'd seen in a while).
That said, this does look half-decent, and I'll be looking forward to watching it.
