I'm a BVB fan and enjoy a good campy movie. But this was a disaster. Where do I even begin? The writing is terrible. All the dialogue is awkward and poorly paced. The story is told mostly in montage rather than actually building a cohesive storyline. The biggest sin though is the use of tacky, outdated, almost offensive character tropes. We have a "magical old Black man" cryptically warning the band as the angel Gabriel (even though nothing ever makes him seem like he'd be the angel Gabriel). There are 3 female characters, and they all only exist to serve our protagonist Johnny. First, there's his mother, whose cancer is diagnosed and cured in about a 10 minute span and she barely speaks again. Then there's a classic "virgin vs whore" trope. Johnny's relationship problems with his virtuous girlfriend is a lazy metaphor for his ongoing corruption. On the other hand, his Satanic evil bass player starts as a normal person, then gets her rape used as a throwaway plot point, then she seduces Johnny (even though they have NO chemistry) and then makes a 180 again back to normal. There's also a blink-and-you'll-miss-it Indian guru running a rehab but not really doing anything.
I could go on, but the point is that this movie starts fun and dumb, then progressively becomes confusing and disappointing.
