Last season, I worried that this series would burn itself out soon with repetition, as any time I look up the long manga series for this, there's usually frustration found with where it is going. I haven't read the manga. As a result, I can't personally comment on it, though I can tell this early on with season 2, that the story is annoyingly dragging itself as a romance, and falling apart. The progression in this 2nd season, plot wise, is like a spider trying to crawl out of a bathtub. The anime staff, for all they are, is the little kid that is trying to help it get out, but lets it slip back down each time.
The comedy, when it works, is all that can somewhat salvage this. The early episodes were very funny, and made this at least entertaining and funny at times. Towards the end, I stopped laughing almost completely. The songs got old since they keep recycling them in a way that it was noticeable to me. The anime ran out of steam with it's humor by the end. Early on, I felt the 100 friends journey for Komi was going to be a character development disaster, and it turned that way. Trying to rush at the end by manifesting people who were never there, and giving them flat personalities only hurt this. The author seriously trying to go with this goal for Komi was a mistake. Look at all the wasted potential for Tadano and Komi. Important events, like those holiday events, when they'd get nervous and look into each others eyes, and Valentine's Day, were all wasted as they are still nowhere romantically. The repetitive formula that they are going to get somewhere but don't, got stale and old since last season. Neither are willing to take that step forward, and it's drags to the extent it's irritating. If you are looking for romance, this is not the series to look for that in.
The staff looked as if they had a lot of fun making this. They tried what felt like everything to try and boost the source material. From wasting the budget on eraser flicking battles and exaggerated details to mundane things the character do, to it's episodic and multiple skits like approach, it felt mostly hit or miss. There might be a skit that wasn't as good, which makes it feel like it wasted half the episode. Sometimes, none of the skits felt entertaining enough, and they tried to make up at the end with a Komi and Tadano moment that of course goes nowhere. Even Najimi, who I felt was among the more entertaining characters, started to get annoying partly in constantly getting in between Tadano and Komi.
The only characters that I came to enjoy by the end were Katai and Yamai. Katai, because his friendship with Tadano that gets often accidentally played out as a gay relationship is absurdly funny in how they executed it. Yamai, because her sickly obsession with Komi is amusing to watch just how far she'll go to get noticed and have her way.
Komi is still frozen in character development, and the constant bug eyed shrieking got old long ago. She's become the bojji of her genre. If this series wanted to use her as someone with a communication disorder, it would help to get her to overcome that as soon as possible to inspire the viewers who can only somewhat relate, as she is often portrayed as the perfect woman; impossible to reality. Still, they won't, as this has to reach 100 friends total, and it's only a quarter of the way there as of now. Tadano is still nothing more than a nice guy who doesn't realize how good he has it, and what he can have if he'd have the manhood to reach out for it.
This didn't motivate me enough to want to read the manga. If there is no season 3, I'm done with for the most part. Season 3 feels like it will just continue to drag, and force the staff to come up with as many more production techniques to try and act like a defibrillator for the dragging plot.
