Superbad is one of the most overrated movies in recent history (right up there with Juno, which I know you all love, too). It is, by far, the worst of the four movies. 40-year-old Virgin, Knocked Up, Forgetting Sarah Marshall, and then Superbad. The first two are close, and then there is a definite drop from 2 to 3, and a large drop off from 3 to 4.
