Out of sheer morbid curiosity, as an autist and a writer, things like this fascinate me. I like to know what not to do and how to avoid it where possible. That doesn't mean it's never happened to me, though, there's been a few times.
Now, I'm not talking about like gay characters in a show and you're not into that thing. I'm mean the media equivalent of receiving a great blowjob and then suddenly you get a finger in your ass that wasn't part of the original offer.
Mine is the show, The Magicians. I knew it would be lefty-leaning because that's just how the books were and the cast was diverse in hollywood's favorite way. That said, I was in for some trash and the fastforward button was for the parts I didn't like. 3 seasons in, I like the dumb plots and the sudden twists, then, the show decided to pull some stupid fucking meta and lecture the audience: Rasheed starts to lecture us that you're a racist, sexist, bigot if you don't watch/read something because the main character isn't white and male. After that, I completely skip a couple episodes, because fuck that bullshit. I calmed down and the first episode I watch, they killed the main fucking character, a white male. Series goes on, I do not. The whole fucking scene was the producers trying to guilt the audience into not rage-quitting the show by calling us bigots. After that, I decided I was never watching another syfyllis network show again, or one with a racially diverse cast, especially no Rasheeds.
Most of that genre has a clear samurai bias but at least they give the losing guy a fair fight.
But this time it made no sense, William fucked up various samurais without any gear when he arrived in japan, he was chosen by one of the lords to represent his clan in a bid to inherit all of japan, and yet gets owned so fucking hard. But it doesn't end there cause they way they describe Yaguy's abilities mean he has an instant kill on any fight going forward and no threat from any of the other fighters since he can learn their styles and use it better than them just by seeing it.
Author would have to pull something out of his ass to make musashi (the likely winner in the end cause he is quickly developing underdog that won his match through a gamble) to justify Yaguy not ending the fight in seconds since his instant kill also stunlocks.....so he can kill you harder
Makes the whole tournament become way more boring.
Record of Ragnarok for example gets over this problem by being a "best of x" style tourney so no matter how OP someone is they will only score the one point and even then the balance is way better (though it has highly nonsensical moments it is fun to go through the fight and learn their backstory)
