21 is a laughably bad movie; it is a fake version of a true story wherein six MIT students counted cards to win big from blackjack tables in Vegas. Except of course for the second and third acts, where things go wrong and become right again thanks to our hero. The story lacked creativity and insight. The writing was atrocious, the characters one-dimensional, the acting flat. Even Spacey was disappointing; while he wasn't bad, he just didn't have any opportunity to be good with the script. The music was always out of place. The scenario was exceptionally unrealistic: who believes that the only way to go to med school is with tuition for four years pre-paid? "Don't have $300k in your pocket? Can't go to med school!" And how can the idiot who believes this have gotten a 44 MCAT?
At the same time, there were a number of parts I enjoyed. Some of the action and exciting moments were gripping. There is one devastating moment in the film, where everything comes crashing down, and I really felt what the character felt. Several of Spacey's lines are brilliantly delivered, especially his vicious insults. The Asian dude is hilarious. It's fun to laugh at, but even then it's not worth it.IMDb link: http://www.imdb.com/title/tt0478087/
