I have always had a tendency to like stories involving vampires, so picking this one up was a no brainer. What I found was an anime with very good graphics, really great action, mesmerizing characters and a highly addictive storyline. The fact that the anime does not follow the manga closely was not a big issue for me. There are some differences here and there and considerable deviations in terms of the order of presenting events, but I thought that the final product in the anime was very good.
One of the main things I liked about this anime is its "cool" main character. Alucard -I still can't believe the translators in the subtitles went with Arucard! Is it that hard to spot the anagram of Dracula? - is a powerful vampire that works for the Hellsing organization, helping solve issues with the undead. He carries a slick weapon and dresses in a very peculiar way. He has a great sense of humor and enjoys facing challenging opponents. On top of that, several of the characters he interacts with, such as Seras Victoria, the police officer turned into a vampire by Alucard, or Integra Hellsing, the measured but ruthless head of the Hellsing organization, provide added interest to the series.
Next, I am going to follow this up with the new set of OVAs released under Hellsing Ultimate, which are supposed to follow the manga more closely and have improved animation. If the original is any indication of the quality of this improved version, I am going to have one hell of a time!
