I can see why recommendations for spicy city has Heavy Metal included. As I watched some of the episodes of this particularly "Mano's Hands", I felt like I was watching something based on Heavy Metal comics (It wouldn't surprise me if any of the episodes have appeared in comic form in Heavy Metal.) I think the reason it reminded me of Heavy Metal was because of the sort of twisted sci-fi look it had and the fact that there was a sex tone to about every story. Almost every episode had nudity either just because someone was just walking around without a top, or because it was put it to excite people. Granted like Heavy Metal the stories in this where usually twisted. Some having humor other just plain messed up I didn't enjoy this show as much as the Heavy Metal movie, but I still found it a good show to watch if you have nothing better to do at the time it's on.
