This one uses running gags about the nature of sequels and the real life identities of the cast. They also bring back the drug hallucination sequences from the first movie with pretty hilarious results. It all works but it is just a little less of a surprise than the first movie. When we all walked into the theater for 21 Jump Street we did not know what to expect.
Here we know the formula. But, to the credit of the filmmakers they take this fact and make it part of the film. The film rolls its own eyes at the inevitability of a sequel to a financially successful film.
One of the funniest segments of the film is during the closing credits. Another? Honestly it wasn't as funny as it should have been because I saw it in the previews. When is Hollywood going to stop with the "every single joke is in the previews" crap?
This is a funny film--as noted--and you won't be bored at any point in it. But there really shouldn't be a 23 Jump Street.
