If you have discerning tastes, don't see this movie. If you need escapism from the daily grind and are not in the mood to over-think anything, this is a good movie for you. It's true; it is crude, much cruder than the original. Most comedies today are just that.
The people responsible for this movie were not thinking lets win an Oscar, they were thinking lets make people laugh. According to the theater I was in, it worked. We were all laughing. I wish it had been longer with more situations, but I enjoyed what I saw.
I recommend not taking your teen to see it. Let them wait till they're 17, not because they are too young, but as a mom it was really awkward.
I will say this about Chevy Chase, he will always be Clark, but keep in mind people age and put on weight. I say so what! The man is funny as hell! This movie will not hold up to the original, don't see it without seeing the original; you won't get the jokes.
