Simon Wolfe writes:
"Hellsing has gotten a similar treatment to Fullmetal Alchemist in that the original anime release of both occurred during the run of the manga and therefore differed from the manga itself. They both also saw a second series, each with an additional word title, Ultimate and Brotherhood respectively, that followed the plot of the manga more closely. Because of this, both original series live in a kind of limbo parallel to the manga and redone anime. In light of this, the re-release of Hellsing as an anime classic a little more than a decade after its original gives the opportunity to look back at the original attempt and how it stacks up today."
