People might say humor is subjective, but some things are really just not funny. After 3 episodes I can count on one hand how many times I laughed, smiled or even blew air out of my nose a little. Every joke feels forced and most of them have no punchline. The so called gag humor this anime is supposed to have are just desperate attempts to randomly catch you off guard but it just makes things weird instead of making you laugh. The only notable parts in terms of humor are pop cultural references, but they're not that frequent.
The show also likes to use Koshitan as a punching bag, constantly. In itself it's not a bad thing, it worked quite well in Bocchi the Rock, but it doesn't work here because this show overdoes it + the unseriousness of the environment makes it boring very quickly.
The best part of the show is the opening and the marketing, it sells you an idea that you get into some silly comedy. Instead you get into a weird, chaotic, uncanny universe that tries to be funny by throwing the most random "jokes" at you labeled as gag humor. It reminds me of the chatoic nature of MLG memes back in the day, but at least that's supposed to be a parody.
Watching one episode will help you decide if you wanna watch the whole thing or not because all episodes are similar and it won't get any better or worse.
