the real selling point for it, I think, was the rock stars doing voices and music for it. it's like they wanted to go one step further than Heavy Metal.
Clearly so. Aside from the technical execution, which is pretty fantastic, there's not much else left. Having the main characters being post apocalypse evolved dogs seems to just be a leftover character designs from when it was originally going to be a kids film. It's a movie that I wished was cooler than it turned out to be. There are some great bits, like the Zero G club and such. The overall structure is mostly mush.
