^all the anger about Mai is like 80% just from people who haven't read the novel and are missing out on loads of character development and backstory for her that the manga hasn't gotten to yet. Unless it somehow gets 2 cours there's no way the anime is getting further than the manga's at now, so anime-onlys are only going to be exposed to early series Mai, when she's at her worst. The reaction is not gonna be pretty...
^Interesting, yeah that can be an unfortunate case with adaptions sometimes. I've had that experience with other series, knowing that a character gets better past where the adaption ends.
