Superbad is one of the classic comedies which left a great effect on R-RATED COMEDY genre, Greg Mottola as a film-maker became a name on the industry with this break-through. I really recommend this movie and a very forceful recommendation if you are a teenage-introvert.
Really good watch, would watch again, and can recommend. I've watched this movie several times, but had a couple different reactions: sometimes I agree this is overhyped, other times I'm completely in line with why it was overhyped. You mood might be a factor in your movie watching, it's all I'm saying. Overall, this is decently funny in dialogue, delivery, and writing. The movie is full of cringe humor and ridiculous circumstance, it's essentially designed so the characters have a good story to tell later on, and it definitely meets the criteria. The big problem is that it's a high school, "let's get laid adventure" starring 2 idiots and their idiot friend. I've never seen 2 guys work so hard to prevent themselves from their actual goal. When you look a little closer too, it's really two movies wrapped around each other. "McLovin" could have been its own movie, but neither story really has enough meat too it. "These high schoolers tried to get alcohol to impress girls for this party." is the whole movie, but it's so much more fun of an experience than that. You're not going to get a rich and fulfilling story, though they try to make it into a life lesson in a traditional "coming of age" style, but it's a pretty funny movie, if a little over the top.
