Review: If you love cult 70's Sci-fi the way I do, or if you like movies such as "Repo Man" or "Buckaroo Bonzai" than you're going to love this one. It's a stream of consciousness 70's Sci-fi spectacular, including a 22nd century junkyard and the Earth a million years from now. This movie is pure 70's. Put on Steve Miller's "Fly Like An Eagle" or Pink Floyd's "Dark Side Of The Moon" and you're ready to go! Question: is it a positive review?
yes
