Berserk
This is technically a show but it is arguably the best adaptation of Kentaro Miura’s series to date (besides maybe the memorial editions). The soundtrack is in fact the best, without a doubt, and if you haven’t experienced Berserk in some form, definitely do so. I think that these series undersell the character arcs, especially Guts, the main character, but that’s only because it’s only the Black Swordsman and Golden Age arcs being shown, and only part of each of those. Either way, this is definitely one to watch.
