Been watching a bunch of things from this season, but my favorites so far have been Majimoji, Jinsei, Sabagebu!, Zankyou no Terror, and Space Dandy. Loving Majimoji the most though, because of it's lovable cast and humor despite the perverted moments. Everything else (Hanayamata, Bakumatsu Rock, Tokyo ESP, Aldnoah Zero, Barakamon, and Sailor Moon Crystal) is average or higher, except for Glasslip which is just a mess. I'm gonna watch it to the end though, to have a full opinion of it. It's not like it's terrible, it's just all over the place in a bad way.
Today I watched Chaos;Head or at least listened to the dub version. It was really horrible and not my cup of tea. I didn't like the protagonist, animes with a harem theme I seldom enjoy and some actions of the characters I couldn't comprehend. Well the worst thing of course was the voice acting.
Yeah, the anime is pretty terrible. I'd recommend playing the VN if you want the real experience, like hypertheory99 recommended. It has a really good creepy atmosphere if you're into that. It also has much better character development and goes into more detail during all the scenes, which is to be expected of a VN. The anime completely ruins both of these things, sadly. Oh, and it also has less of a harem theme to it. Although, you say you didn't like the protagonist, so maybe it's not for you. Your choice.
