Hellsing Ultimate makes a good argument for wishing the Japanese DVD industry as a whole to commit seppuku. All their stuff is like that, and they want us to settle for it, as well. Plus, they only release it on a somewhat yearly basis. But I don't know how that works now, since Geneon was helping pay for that, and they, like, died a couple years back. Funimation did the fourth and re-issued the first three, but the most recent installments haven't made it over here. Hopefully that means Funimation is planning to make a more sensible release format. I hope so...it's good stuff.
I'm currently re-watching GTO. That's pending the Netflixing of the second half of Dragonaut, which I describe best as "pretty crap" but like it anyway.
