I’m going to go to bed in a while, but before I do, here’s a little PSA.
If you seriously dislike Osomatsu-san more than like it; if you seriously dislike the show’s brand of humor and think it’s too much for you; if you seriously dislike the characters so much and think only a few to none of them are remotely likeable; if you seriously think the character design is bad; if you seriously think that Studio Pierrot is ripping you off and that there’s truly nothing about it that makes it worthwhile…
I have a suggestion for you:
Please, please, please, for the love of all that is good in this world…
Seriously, if you dislike the show that much, feel free to drop it and find another anime more suited to your tastes. There are a lot of shows out there with more wholesome characters, a more wholesome sense of humor, etc. You really don’t have to stick around to bash every single aspect of the show, its characters, its humor, etc. We can do without it.
(And no, I’m not saying the show is above criticism, but there is a difference between constructive critique and full-blown nitpicky hate and I know you know full well what I’m talking about.)
If you really truly feel like this, do yourself (and the rest of the fandom) a favor and leave. Find a show that better jives with you, or make your own original stories suited for your tastes. You (and the rest of us in the Matsu fandom) will be much, much happier for it.
