From what I've noticed, most people I know who have never done/been involved in cocaine or something similar think it's very over-rated while those who aren't exactly on the right side of the law love it. Personally, I just don't think it's aged very well at all.
As for an over-rated movie, while I think the first Spiderman was really good, the people around me hyped it to no end so that's the first movie that comes to mind when I hear the word overrated.
