The film is meant to be a nostalgic, breezy and unpretentious musical; indeed, its best qualities are its lighthearted charm and memorable soundtrack. The trouble is that it doesn't have much to offer between songs: the characters are dull, there's no real meat to the main story or subplots, and the humor is quite corny. Films like these don't always have to be challenging or insightful, but SOME substance is needed.
A guilty pleasure of summer lovin' and grease lightning. Impossible to take serious nor is it good nor bad enough to ruin anyone's night. Songs have been overplayed so much on radio that it is hard to feel anything good about them anymore and this has taken away some of the freshness from the film.
Serviceably filmed, but it's the music and playing that makes this one displaying tremendous bounce & joie de vivre. It's all very conformist with teenage rebellion redacted to no more than pimples of bubblegum-blowing insouciance. However as tableau of staged songs of faux 50s Americana (reminiscent of how people lined-up to fill the screen in CinemaScope), it's decent fun and very much part of the furniture now.
