Komi Shouko is a beautiful girl who immediately becomes the most popular person in her high school but is held back by her communication disorder and anxiety that makes it almost impossible for her to talk with anyone. Her goal is to make 100 friends while in high school and is helped by the first friend she ever makes, Tadano Hitohito. The premise is interesting enough for a slice-of-life show, and it almost sounds like some kind of romance/shojo series, though the main focus is comedy.
The biggest question is obviously whether or not the show is actually funny, and for the most part, I would say it is, but I think that really depends on the viewer. It tends to use a lot of situational humor and gags, going for a kind of zany/wacky feel, almost as if it's telling the viewer, "Look at how weird these characters and situations are! Isn't it so ridiculous and funny?" It's not a show with incredibly well-structured punch lines, setups, etc., moreso being a thing where you just sit back and watch whatever unfolds. It's definitely entertaining, but the most it ever got out of me was an occasional chuckle and some smiles.
Many people have said that the show gets very repetitive, and I honestly have to agree. It does rely on the same sorts of jokes and situations over and over again. You learn to expect it and grow comfortable with it, but more diversity would have been appreciated.
The characters are alright, not great, but not bad. They're basically all defined by a single character trait, with Komi being cute and awkward, Tadano being "average," Najimi being quirky, Yamai being obsessive, etc. It is a comedy show, though, so I guess that's forgivable. There are also a lot of underused and kind of pointless side characters that pop up now and then without really doing anything. A lot of the focus and humor are centered around Komi, so if you don't like her or find her interesting or relatable, you probably won't get too much enjoyment out of the entire thing.
If you're thinking about checking it out, I'd say watch the first two or three episodes. If you don't like those, you definitely won't like the rest of it because, as mentioned before, it is just the same kinds of jokes and situations repeated again and again.
Komi-san is pretty average in the scope of the slice-of-life and comedy genre, but it's pretty enjoyable nonetheless.
