Claymore was a decent series. If you're gonna watch Hellsing watch the ultimate remake. Much better IMO. Still 1 episode left to go I think. I haven't seen a good gorey anime in a while. For me it's been mostly mahou shoujo type stuff. Or the borderline hentai type stuff like Queen's Blade. I'm just weird like that. They don't seem to make many good action series anymore. Nothing like Berserk anyway.
