Entertaining!

Rating: 8/10 (24 January 2005)

Jack Black plays a rock musician that gets kicked out of his band prior to the big battle of the bands contest. Unable to hold a job, Jack is pressured to pay up or get out by his best friends wife (Jack rents a room from them). Other than his music, Jack has no ambition towards work until he happens to answer the phone from his friend. It seems a school needs a substitute teacher and will pay well for Jack friend's services. Jack pretends to be his friend and goes to the school posing as his friend.
The school happens to be a very upscale and exclusive private school. What happens the rest of the movie is totally unrealistic, but entertaining nonetheless. Jack is assigned a class and he sits in the front of the class being totally obnoxious with the kids and teaching nothing. By chance he happens upon a few of the kids in music class and realizes that they have talent. He cooks up the idea that he will be able to teach the kids how to play rock music and then go to the battle of the bands contest with the class.
If you can dismiss how such a prominent school doesn't verify the credentials of its faculty (they don't ask for a driver's license, social security card, etc. that jobs are required to hire you), can't hear the loud music blaring down the halls, uncaring parents, etc., then the movie itself is highly entertaining.
