At first it was very, very confusing. I seriously thought I missed some episodes in between, but no. Thing starts off, things happens and the characters are very hard to grasp. It's like when you walk in the middle of a story.
Then things stats to get better, I actually enjoyed a few episodes and then things get aweful. I mean, it was a pain to watch the characters go down in a pathetic spiral of 'death'. No one dies, but you'll wish they did instead.
This anime brings down all the aweful things that can go wrong in your life on a character that can obviously not take any of this and just "goes with the flow", not even fighting it.
Painful to watch and confusing most of the time. Some say it's a masterpiece because it makes you cringe, but countless other anime does that and are better than this.
