22 Jump Street. Egads, it was even worse than 21 Jump Street. Which is to say that it was even better. Or worse. It's hard to say, because the movies are stupid, and I find them entertaining, but they're also completely self-aware, and a lot of the humor comes from that. So is that meta-humor? I don't even know. A lot of times, I found myself laughing because something was so completely stupid, but not in your conventional "so bad it's good" way; it was just bad. But so bad that it was funny.
Example: Constant references to the fact that it was the exact same case as last time, because this movie has basically the same plot as 21 Jump Street. But then the big break in the case comes when they realize that it's not exactly the same, and that they've been so caught up in that assumption that they failed to see how it's actually different this time, and that leads them to solving the case. So the cases are different, and that makes this movie different, even though they're the same. So confusing.
