21 Jump Street ★★★½

One part buddy cop movie, one part nerd high school power fantasy, and one part raunchy teen comedy. It's easy to see why this movie was such a hit -- its leads have great screen chemistry, the cast is full of likable actors, its directors have a strong grasp of character, and it's genuinely pretty funny.

It doesn't do a whole lot to break the mould in terms of teen comedies, but it's a rock-solid piece of entertainment.
