This movie is very well done. They film it perfectly, with cool angles I've never seen done before. The violence is bast on real events, (they play 'poker?' but these people above the billiard room beat up anyone that cheats like these 12 graders who have know idea its illegal.) Its often funny with lines of 'I need a drink' and two people from the same team begin making love on a train. (anything strange about that? Nah, I see it every time I go on a public train. LOL.) Theirs drug, and a seen when a man is beat up very bad, blood every where. B.S. is said and God- D*** is heard. A girl smokes and drinks 'trying for a sexy look'. Los Angelas is shown lots of times. That includes clubs, gambling rooms, strip club etc. Theres nudity nothing shown from a window. They cheat and are filthy rich from counting cards, which by the way is illegal. Blood is shown on a camera. No good role models, except at the end when they realize what they are doing is not so great as they thought it was.

Some of the main actors, such as Jim Sturgess and Kate Bosworth, will appeal to younger audiences, but perhaps think twice before taking your younger teens to this Vegas film. It's fun and it's inventive and you shouldn't miss it - but there is excessive drinking, partying, and the like. Language is mild (s--t was used a few times, but that was the max.), and there are brief romantic interludes, but other than that, 21 is a must-see. (:

Almost EVERY PG-13 Movie on CSM is either pause for 14 or pause for 15. A 12 year old could see this! Yes, they do make love but partial nudity!?! Come on! you see there neck and up! It is fine. The only thing is that there is a bit of cursing. NOT THAT MUCH! It is fine for any 12 year old to see this. GOD!

Come into this movie expecting not a heroic, original plot. Kid gets rich, gets broke, finds revenge, nothing you haven't seen before. Plus it's way too complicated for any "math genius" to understand, the card-counting. But it is worth it in the end.

I mean it's a Vegas movie so you know it's not gonna be a kid's movie. Despite that, I thought it was a good movie and made me feel like playing 21!

I thought "21" was a very entertaining film. It was amazing how they could make something as dull as blackjack become exciting and thrilling. The sexual content wasn't that bad. The social behavior was at times unrealistic because most people just don't go around being THAT smart and being able to count cards but that made the movie even more interesting! I would recommend it to anyone who like the Ocean's movies or anything of the sort.
