The best movie musical of the late 20th century!
By FAR! The catchiest songs, the best leading performance from Moranis, the most scene-stealing supporting actors, a story that's genuinely gripping, the most laughs, the AWESOME plant effects, and of course the wonderful "Greek Chorus" girls that totally fit in with dark theme under the comedy. It is a great film and totally original, that manages to perfectly carry off exaggerated comedy and make-ya-wanna-dance music, while a man struggles for his soul.
I don't think there were any better musical films made between 1970 and 1999, or 1960 and 1999. Maybe there were a few better ones in the fifties, before the Studio System went bust, but for the post-studio era this is it.
