This is an excellent TV series, not as bloody as the films but it is more faithful to the original Manga books.
My biggest criticism is that Media Blasters are only putting two episodes per disc. Apart from the cost, that's an AWFUL lot of DVD's taking up shelf space.
The good news is that there will be a box set, the bad news is it could be some time coming.
Even though I have bought the first two releases (and enjoyed them enormously) I think I'll wait for the Box Set.
