Steve Kimes’s review published on Letterboxd:
A glam rock musical version of Phantom of the Opera, Faust and Dorian Gray, with a healthy dose of kitsch thrown in. It's hard not to smile at this film, there are so many throw away references to classic horror films, and some songs that are quite good. This is the first feature by Brian DePalma, and it looks like it. I wouldn't mind if he would redo this film, with his cinema skills honed.
Too much fun not to enjoy.
