havent seen it yet, but trusted sources are saying its very pretty and the story is strong but its slow and the action is good-looking but not particularly "action-ey".
Besides its supposed to eb a loose sequel to the filsm and the relation to the comics has been tenous at best since the first film, its a seperate canon of work which just uses the parameters of the comic... the scale of the comic world is just too big to faithfully translate to screen... same as X-men and all the other comic-properties on film.
