In case I didn't mention it before, the BD xfer of Heavy Metal is pretty good IMO. The contrast, color and detail on the BD were noticeably better than my old 2003 Superbit DVD edition. It's possible that the 2008 DVD Collector's Edition could have been mastered from the same HD xfer as the BD though, so the difference between those two versions might be a bit less striking.
IAC, this BD release gets a strong thumbs-up from me. This is intented for mature viewers btw.
