    If you think the plot of "21" sounds as if it was slyly brushed out of screenplay purgatory, just wait until you see how bland the movie actually plays out. For being a group of renegade college students, the characters really aren't very interesting at all and the actors constantly allow Kevin Spacey to steal the scenes, even when he's in the next room getting coffee. Props to Jim Sturgess for giving some especially bad narrating, too. If anything, though, the movie's effective editing does do a good job of capturing the excitement and tension of counting cards as a team. Expand

    Someone should remake this film. The book was amazing, but the movie didn't seem real, too Hollywood. Was the end slow walk shot with all the characters really necessary. It also seemed to ignore the whole part that he was still a student while this was going on.

    Interesting enough to watch but it didnt do well to hold interest through out and it got really boring. Acting was ok but I expected better from the experianced cast. Just wasnt that good.

    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.

    Escapist moviegoers happy to live out a flashy fantasy get a brief comeuppance and still walk away from the table with a little something in their pockets.
