This rousing foot-tapper from the pioneering American film-maker Luis Valdez is the definitive Eighties music biopic.

The film feels curiously devoid of passion and lacking in curiosity as it hits every predictable beat from start to finish.

Sweet and serious, a fine little movie that accomplishes just what it sets out to do.

The movie paints a respectful portrait of the clean-cut kid while providing much of the dramatic conflict through the character of his hot-headed brother.
