Beserk doesn't need a remake, it just needs an ending.
I don't particularly like the idea of 'remakes', most of the time- if the show was good the first time around, why risk ruining what made it special by trying to update it? If it wasn't good, why waste the time on something that was junk to start?
Exceptions, of course, can be made for fantastic manga with terrible anime- since you know, if handled right, it could be awesome.
That said, I suppose if I were to pick a 'dead' franchise I'd like too see more of, I'd pick Eat-Man. I really enjoyed the Eat-Man manga back in the day, but neither of the anime really seem to capture the same 'mood' (especially Eat-Man '98, that was dissapointing. The first series wasn't bad- kinda weird, but not bad.) I don't care about a 'remake' though- new material is fine as long as it's true to the source.
