Refreshing, entertaining, and very well done. Channing Tatum and Jonah Hill work brilliantly together! And of course, a quote from Ice Cube has to be posted! "Clearly I wasn't talking to you, big-titties. You cherub-looking motherfucker. I was talking to your partner, fake-ass Handsome McGee here. When I'm talking to him, I'm talking to him. When I say "shut the fuck up," I'm talking to you."

This was so much funnier than I expected it to be. I had tears in my eyes. Just what I needed. Hill and Tatum have good chemistry working with a solid script. It hits all the usual notes and does it well. I enjoyed the fun cameos too. It's a shame the late Steven J Cannell isn't alive to see what became of his creation. Jump Street and A Team make it 2 for 2, I'll take a Greatest American Hero or Wiseguy next thanks.

Terrible movie... If you have any idea about what good and bad is, then you would definitely not want to watch this crap movie... 1 rating from me...!!!

Although this looked, by all indications, to be just another empty cash-in on a familiar franchise from thirty years ago, in reality it's a completely self-aware semi-satire that's funnier than it has any right to be. Jonah Hill and Channing Tatum take their roles about as seriously as the film does itself (read: not at all) but still manage to develop a weird sort of chemistry as a helplessly stupid, modernized odd couple. It's to be expected that they'll stumble and bumble their way to the head of a major criminal organization. But rather than trying in vain to avoid the cliches inherent with such a familiar premise, 21 Jump Street completely embraces them and actually dictates its decision to do so. Maybe the best example of this is in Nick Offerman's all-too-brief cameo, as he stares down the lens and deadpans a monologue about recycling thin gimmicks from the past. For storyline purposes, he's talking about the department resuscitating the Jump Street undercover program, but it doesn't take a grin or a wink to know what he's really on about. He grins and winks anyway. As a parody of everything from its genre to its audience, this is pointedly effective stuff. It struggles to develop into anything more serious, but that's not really the point.

It's FUNNY and very re-watchable, especially if you like any of the actors.
