    This film is so interesting, the trama, characters, story, is wow, a bigger sorprise the performance of Kevin Spacey is amazing, I think that this film is like the others. 21 is a classic.

    21 drags itself to a climax that puts credulity in splints. So what? In a multiplex of dumb-luck hits, it's a kick to watch Spacey and a gifted young cast use smarts to deal audiences a winning hand.

    Spacey's engaging for a while in one of his patented double-edged, sharky roles.
