Very similar to Ralph Bakshi animation and Terry Gilliam themes
I can't believe that Ralph had nothing to do with the animation! It almost instantly reminded me of Cool World.
On the other hand, there are so many themes here that tie into Terry Gilliam's work (especially Brazil) such as the cynical and satirical future, industry that sees workers as unnecessary evil, flexible boundaries between the real and the imagined, (un)real love as the only comfort, the ambiguous ending and so on.
If you like this movie and have never heard of the aforementioned two names, you'll want to get introduced with their work.
