Finally saw this movie, pure brilliance. Basically felt like the tv show "Undeclared" all over again. It's so rare that a successful mainstream comedy is so good, and ever rarer that a romantic comedy is a decent movie, but he successfully pulled off both into one of the funniest movies ever. I may see this a second time in theatres. I also love that he was able to include SIX of his stars in freaks and geeks/undeclared. Seth Rogen and Jason Segel are brilliant.If you liked Knocked Up, you should rent "Freaks and Geeks" and especially "Undeclared" on dvd, it's got many of the same actors with the same writers and director and they're great shows.
