So I heard a lot about hellsing. Thus I was really excited to watch it. But when I did started watching the anime I was really bored. Now the anime does have some cool actions and good dialogue and Alucard(MC) is really cool. But the story telling of the show is really bad. And they never go to the back story of Alucard at all. Plus if you add the total screentime of Alacurd in the entire show it will be equivalent to i think 4-5 episodes. And to top it off since the manga wasn't finished when it was released the ending was terrible and left on a cliffhanger. It was probably planned to have a sequel but it didn't get it. I would rather recommend watching "Hellsing Ultimate" which is like a thousand time better.
