    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

    This true story is not only an intelligent movie, it also has a great cast, especially Jim Sturgess, playing the main character. It has a great twist ending, and deserves better critical recognition. It proves that a bunch of nobodies (and Kevin Spacey) can make a great movie. However, it's nothing like the book, which was a little disappointing.

    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.

    This movie is simply average. The acting isn't really mind blowing even though Kevin Spacey does do a very good job. A lot of the scenes are also very well shot but when it comes down to it the story was actually very predictable and the romance between Ben and Jill seemed very forced. The movie is worth checking out if you catch it on TV or can borrow it from a friend but don't spend a lot of money buying the DVD. Expand

    A well story based on true events (although changed for obvious reasons). The MITs students do a good job and Kevin Spacey is showing his acting skills again in this film. Overall a suspensful film!

    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: Jim Sturgess stars in a stacked tight cast in this delightful, thoroughly entertaining, mysterious dramatic film experience alongside Kate Bosworth, Laurence Fishburne, Kevin Spacey and Aaron Yoo. A math professor, Mickey Rosa, takes 5 M.I.T students under his wing to count cards to make some money in Las Vegas. Remember, it is not illegal, it is only frowned upon. When a brilliant student has to earn cash to find his way to Harvard Med, he takes a chance on the elite mathematician team. Lucky enough for him, a spot has just opened up. With ruthless casino bosses, ignorant teammates and romantic flares, all make for a great story of luck, romance, betrayal, impulse and of course genius capabilities. What would you do to get into Harvard Medical School? Expand

    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.

    It's definitely interesting, but It desperately lacks an element of relatability within its lead and supporting characters.

    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.

    21 has a few tricks up its sleeves.
    The movie is smart, interesting, and inventive. The acting is poor, but the script is pretty good. I could have wished for a better ending, but the film is sound.

    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. Expand

    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.
