Copy-pasting:
I guess I'm in the minority when I say that Oregairu's story is overrated like crazy. I find most of everyone's dialogue is presumptuous to the point of edginess. It's as if a 14 year old emo wrote the script. Nobody talks like this.
Even though he's self-described and acknowledged by everyone as a "loner", the main character is surrounded by people who rely on him and actively try to be a part of his life, having more relationships than anyone around him. The plot progresses through the solving of problems which only need to be solved (by our edgy smart hero of course) since apparently everyone on the vicinity of Hachiman has the social awareness and pro-activity of an amoeba.
So, basically I'd sum this up as a bland edgy boy and his harem which has a 50% chance of increasing every time he acts normally towards a girl.
This being said, season 3 has definitively shown improvement but it's still bland drama.
