Hellsing is a fairly unique take on the vampire mythos in anime. The art is done in an unusual style, more abstract than I would normally prefer, and somewhat repetitive. The characters are intriguing if occasionally hackneyed. Although it’s hard to pack much plot into individual episodes, due to time constraints and the need for cool visuals, there is a metaplot that develops throughout the episodes that looks to be going somewhere interesting.
Fans of vampires and anime will find much to enjoy about this series, which seems to combine some of the best of both. However, there is definitely better vampire anime out there, including the classic Vampire Hunter D and Vampire Hunter D: BloodLust.
