Great movie! Loved it when I was younger. Got more of the jokes as I grew up. Some sexual humor and situations can get bad. The language isn't horrible. Drugs are kinda bad. Including some drinking and a marijuana scene. Also, once again police are portrayed as deceptive and not helpful. But a good moral, some positive themes, and a great ending, give this flawed film that 'buddy comedy' feel. It, sometimes, feels like a kids film with some inside jokes, winking at the parents...then you get half way through the film. "I ate a brownie once" "I bet they're dancing, naked, wet...right...now" "this never leaves the cave." The sexual content gets bad at times, and I'm not saying that the redemptive themes "redeem" this film. It's like a pretty vase. On the outside, it's pretty and cool-if you overlook the flaws-but don't study it or think at it too hard, or you'll see the empty, dark, hole in the middle. Where some more structure needs to be, some plot holes need to be filled, and some flawed scenes need to be taken off.
But all in all, good film, good for some 12+ and 'on' for 13+. Classic in my opinion.
