I just bought Vampire Hunter D:Bloodlust (having originally watched Vampire Hunter D and found it a quirky but generally quite poor example of the genre).
This one was better in every way, beautiful animation and backgrounds, including some spectacular castles, a decent plot (although the twist could be seen for miles) and a very cool central character.
What manga/anime do other people like? Any surprises or little known films?
I have Cyber City Oedo 808 and Ninja Scroll in my collection too, and rate them highly as well, plus all the usual Miyazaki stuff.
