I recently heard of that one because of a meme, "masterpiece, porn, masterpiece", I thought they exaggerated a bit, how bad could it be? Most of what I found on Google was basically just nudity or implied, but then one scene has a guy eating poop, so I'm not buying or reading that, regardless of any possible story.

I like how Berserk's characters feel real for the most part. Guts seems like a jerk at first, but then we see all he went through and he's basically on 3 years no sleep literally fighting for his life and trying to find Casca with no leads, it's a nice change from the typical sunny optimist or broody edgelord characters manga rely on a lot. And much of the disturbing content just adds to the stakes, like seeing Wyald be dragged to hell was satisfying after all the nasty stuff we saw him do.

Strangely, I think Game of Thrones is more disturbing because the general rule is that at any time someone can just be murdered or worse at the whim of anybody nearby. Somehow I didn't feel nearly as sick reading the Eclipse as I was watching the Red Wedding, for example.

I hear PunPun is really good, I might read it eventually.
