The Berserk anime was a little dissapointing compared to the Manga. That shit was unreal. Got the whole series, and it's still one of the better anime's I think, though like all of them really, compared to the Manga it ain't so great and things get lost in translation.
Gungrave is weird. I can't really get into it.
The re-made version of Full Metal Alchemist is actually pretty good. I generally don't like the CG enhanced versions, but they went and changed the whole story line towards the end, so it's basically a different anime. Though with the same base story.
