ON THE OTHER HAND, I did not like the way he would never confront anyone or do the right thing /when/ he should have done it. It became very frustrating. Especially with the way he kept getting insulted. I can't stand spineless characters or characters who don't DO anything.
For me, the fact that he was so... passive, always watching things and barely doing anything to alter the course of the story, made this a forgettable story. As I said, the characters are likeable, but I never had any moments where I was cheering inside or happy. The storyline isn't anything great.
There wasn't anything there to make this anime worthwhile, especially as all of the story's realism and "perceptiveness" was wasted on a main character who was so uninteresting to follow around.
His behaviour was/is so out of sync with what an analytical but INTERESTING guy might have done. If only he'd been more like the main character of a series like, say, Log Horizon and a) been more upfront about his feelings, b) been more active when it comes to helping people, c) USED his analysis of people's characters to do something, rather than sitting around and waiting for the others to fix things, etc. Then this would've been a 10/10 for me.
Alas.
I've got other qualms with how the story threads were dealt with and how a lot of characters weren't developed enough or in an interesting enough way, but I'm not going to sit here proposing how to redraft the entire anime :P
TL;DR: The MC just isn't a main character. There should've been a different main character with motivation an a spine, and the current MC should've been relegated to being a background character... his rightful place.
