I know a lot of people love this. So I'm probably the asshole here.
To be absolutely fair, it is exactly what it claims to be. Some stunts and some rock. The stunts brought to us by Australian Grant Page and the rock by Rocktober Blood's house band Sorcery. Where it gets in trouble, at least for me, is when it claims to be a movie. There's some semblance of a narrative throughline here, but I don't think anybody really cared about it. It's mostly just vaguely disconnected concert footage or Page's stunt reel, playing out for us to view.
Maybe some other day I'd be into this nebulous, shambling mess of ideas, but I just wasn't feeling it at all. I've seen Godfrey Ho stitch together disparate ideas with better results.
Are the stunts cool? Yes, obviously.
Do the rock sequences rock? Absolutely.
Is that all you need to make an amazing film? I'm not sure about that.
