I checked out the first 3 Volumes of
Berserk. Good lord, you guys weren't kidding. It's unapologetically dark, and carries a visual detail during the action scenes that isn't seen very often. Guts himself shows his Kratos-y side even moreso in the manga due to a
certain tagalong companion. There's obvious contrast between the two. Someone who feels emotions so intensely, and someone who's either devoid of them, or supressing them entirely.
Considering his upbringing, I'm not entirely surprised how he turned out. He's someone who was literally born in a world of battle and blood from day one. He lives for passion, himself, and not much else. There
is a certain level of theming and depth, but it's still an action-heavy dark adventure first and foremost. Watching the anime of
Berserk would be equivalent to playing a video game based on a movie - you're not really getting the full experience(or at least based on the episodes I'd seen).
It's a damned good Manga.
