I often describe Finnish culture as containing a Fairness Kink which definitely would apply to this situation among others.

I feel this way sometimes even when I'm not planning to share criticisms publicly with anybody (like, maybe ranting to my wife or my bff, but not like... posting about it). It applies if I'm even going to decide that I hate it most of the time. - I don't necessarily have to see every movie that I get the impression I would dislike from other people's reviews or whatever, though - just the ones I would otherwise feel invested in, like from fandoms I care about or whatever.

In the case of the She-Ra reboot, though, I think I maxed out after finishing the first season... initially I was planning to watch all of it to maintain fairness, but after feeling sick with dread for a couple of weeks when they released the second season I changed my mind.
