Filme fraco, o roteiro é ruim, as cenas são fracas, a história é fraca, o elenco é fraco, e ninguém ajuda a melhorar o filme, os personagens sao ruins, e o filme deveria ter cenas bem melhores e relevantes, para fazer o filme ser bom.

Interracial jokes and mysoginy.

Referência ao saudoso “Vigilantes do Peso”, dublados do Professor Girafales... Bem cara dos anos 90, apesar de 2005, aqueles filmes cômico policial investigativo disfarçado, clichê, apesar da tentativa quase frustrada de criar um mistério em torno do verdadeiro assassino bem como sua motivação, personagens cotidiano, comunidade escolar e policial automática e rotulada, piadinhas simplórias, engraçadinhas, filme regular de passatempo leve e não pensante...

Pretty rotten. The plot wasn't bad (although it's been done before and will be again), but the main character, Nick Cannon, was just awful. The jokes didn't land. Corny.

I didn't really like this, but I think that undemanding audiences will! Definitely not as bad as I was expecting, though, what with the 6% Critic Score, here on Rotten Tomatoes!

This movie has Roselyn Sanchez and Kelly Hu, this is the best movie ever.

The Rotten Tomatoes consensus says it all, so no need to explain in full detail about my hatred of this film. The funny (and probably ironic) thing is that the film adaptation of 21 Jump Street did a better job portraying a rowdy, comedic take on the show's premise seven years.

Loved this movie, under all the cheap scenes and whatever else, there was a great story and good humor, cant wait to watch it again!

If you are Crazy about Nick Cannon, this might be the movie for you.

Average movie- Nick Cannon coulda done better but hey I ain't no actress myself! He comes out better at the end gaining the respect of his colleagues all because of a hunch and he gets himself emotionally involved with one of the culprits stealing flash cars. Good movie because Nick has to relive his school days- posing as an undercover cop and any plot to do with American schools is all good!

It could have been funnier.

quite the declaration to be like Mike.

Pathetic. Kinda funny and a bit touching in a few places, but generally just very dumb. It probably didn't help that I watched it with the dialogue and action not matched up, however.

It was better then I thought it would be.

Kelly Hu was underused in the movie as was Roselyn Sanchez. It was still enjoyable though

"This is one of those movies where at the end of the year you'll say, 'Underclassman, what was that about? I don't even remember it."- Richard Roeper I just watch and I can't even remember what it was about! It was so boring

This movie sucks so much my grandma was making fun of it.

cheech marin's reaction to his new ride at the end topped it off hahaha

enjoyable if you have nothing else to do...

This movie was far less cheesy and over-the-top than I expected it to be. It's not an original story by any means, but it's still entertaining and worth the hour and a half. Nick Cannon is a far better actor than he is a musician.
