The TV series not so much. It was made right after the manga had started and went completely off the rails about halfway through
The OVAs, Hellsing Ultimate, are fantastic. Top tier in every imaginable way. You have not seen anime until you have seen an immortal Nazi who has spent the last 75 years living in a secret antacrtic nazi base monologue for five minutes straight about the beauty of war to an army of vampire Nazi super soldiers.

Also it is one of the few animes were the oblivious MC ends up getting a clue and realizing best girl is actually in love with him and acts on it.
