I don't remember much of the specifics (no context + I start skimming whenever that sort of rant turns up) but there are a staggering number of people on Discord who seem to enjoy ripping it apart, in part because it's fun and lighthearted (and it's not Madoka Magica). I tend to philosophically disagree with these folks about a lot of other things, so I take their criticism of the show with a huge grain of salt, but wow, was that unexpected, especially when I'm not even in a space devoted to that show in the first place!

IIRC, this came up in a discussion of a Madoka/ML crossover, which people had very strong opinions about how to do it "right"...
