    The movie's chief audience, consequently, will probably be gullible and young, responding to the cliches only because they haven't seen them before. They have a word in Vegas for these people: Suckers.

    A movie that wastes a lot of time and money and really, REALLY shoulda stayed in Vegas.

    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. Full Review »

    While the first half of 21 is interesting, fresh, and gives us a glimpse into the minds and everyday lives of this card-counting team, the second half resorts to melodramatics, Hollywood clich├ęs, and a very "movie-like" ending. The one saving grace of the movie is, of course, Kevin Spacey. In fact, he's the reason I watched it in the first place. Full Review »

    As far as true story gambling movies go, it is pretty good. Even though the plot is predictable and a little dry, the acting and the direction is well done. The explanation of exactly how the counting cards system works is helpful in understanding what is going on in the movie. Overall, the movie doesn't pretend to be anything that it isn't. Kevin Spacey is excellent and Jim Sturgess does a good job playing an innocent youth that is corrupted for the first time. Full Review »
