I don't hate circus but its clear the people obsessed with it haven't seen or read much media outside of cartoons. It's formulaic and basic and it doesn't really do most of its tropes that its doing that well to the point it has over 1 billion views.
It's not even utilising the concept of the show based of No mouth of them being trapped that well, besides episode 1/2 the show itself barely addresses this instead opting everytime to have 1 on 1 therapy sessions rather than showing how awful it would be to be trapped or be unable to do basic things like swear or have sex and the effect that would have on the characters.
It's all done in the most basic tumblr pandering way where no one is allowed to be too awful at the risk of not being able to sell plushies of them, the whole thing feels very cynical. It's not awful or anything but the fact so many people are sucking it off proves pandering to online autism fanbases with "lore" and a shit ton of merch works
