Watching AoT for the last several episodes has been an increasingly masochistic experience, for lack of a better term (sounds way too extreme/melodramatic). The characters you liked turn into retards and scumbags, and the bad guys get framed as good guys. It's an interesting inversion, but it doesn't feel like it's well written enough to be convincing. The characters turned on a dime, it could've worked better if the transition was slower or a bit more justified.
Thinking about it, there's no way Isayama isn't trying to piss people off, it's clearly trolling of the highest order. I remember seeing some weird quote where he says he wanted to "hurt" his fans, so it seems intentional.
I can sit back and just watch the show do whatever, I don't get invested in fictional characters to the degree that I'll take something personally, so any direction this plays out in is fine. I have my criticism and preferences but it's still enjoyable, just in a sort of weird way. But still, fuck Gabbi. Such a stupid, obnoxious little Mary Sue cunt.
Correct me if I'm wrong, but I don't think anybody fucking likes Gabbi. I think Isayama knows it too, so he has her shoot that girl (forgot her name), blow Eren's head off, and shoot Floch. This latest episode just confirms to me that she's a literary tool designed to troll, she has no bearing on the actual direction of the story and exists solely for moments like those.
