I've been watching Hellsing Ultimate (a few years later I know) and loving it
It's been fun going back to Hellsing although some of it was a bit
It seems much bloodier and more involved than the original Anime, with better character progressions, and goes so much further with the story and it pays off.
I've enjoyed the Dub (it's one of the titles where to me it makes sense to at least try the dub), and the commentaries have been fun, especially where they get into some of the background of some of the decisions on how/why they did certain things, there is a comment about how they almost lost the chance to dub the original because they pushed a query about pronouncing Alucard as "Arucard" and the Japanese Geneon execs were not happy, but when they spoke to the creator he was basically "I'm sorry if my English spelling is wrong, correct any mistakes and make it cool"
(the dub director sounds like he did a massive amount of research both on the Manga/Japanese intent and source materials).
I think the main reason I haven't seen it before was because of the long time between volumes, and from memory it was being released at about the point the industry in the US and UK was falling over so I was unwilling to pay for 1 or 2 episodes at a time when it looked like it might not get fully released (I was buying several UK releases about that time that kept stalling - I think Tsubasa Chronicles and Witchblade both got mucked about as I ended getting about 3 copies of disc 1 of Tsubasa in different forms before the full set was finally released).
