“This is awful” doesn’t come out of the mouth of someone fully consenting.
Also it’s perfectly reasonable to complain about something when you’ve read the previous story and the sequel is so different, so don’t give me that bullshit about “if you don’t like it, don’t read it”. I did like it, and now I don’t, and I want to bitch about it, which is what the comments are for. Maybe people pointing out the flaws makes you feel bad for enjoying something and then realising it’s problematic?
