The easiest way to summarize my feelings for Berserk is just mixed. I think my main problem with it so far has been that many story lines feel almost like filler due to the pacing. The villains are another issue--I find most of them cheesy, dull, borderline Shounen, and reeking of filler for whatever reason. I wasn't even impressed with Zodd. Skull Knight seems cool so far, but to have only one "villainous" character that you like after reading 100+ chapters is very disappointing.
I was reading through the first few pages of this thread and saw that people were loving the Band of the Hawk members, their friendship with Guts, and their characterization. I felt the opposite. I don't think Miura is very good at character building. Aside from Guts and Griffith, none particularly held my interest. When all of his companions were dying, I thought it was awesome, but I didn't care, per say. I didn't even remember any of their names, and their "characterization" was limited to a few scenes and flashbacks throughout the entire arc. My biggest problem, though, lies with Casca. I have a problem with the way Miura writes female characters. At least for now, as I haven't read the rest and can't say whether or not that's changed. I'd go into detail, but I don't want to bog this post down too much. Let me know if you want to talk about it.
Overall, while I think that Berserk is very flawed so far, I still really enjoyed the arc. It's exciting, the art is amazing, and Guts is an awesome character, so that's more than enough to keep me reading. I want to buy the merch now just because of how cool Guts is.
