There's a bunch of narcissists who make up the fanbase although they've been turned into a meme by trolls on reddit.
Also with the release of season 3 this year, they started harassing and doxxing the female writers with GamerGate levels of retardation because they thought the season was subpar because of them, which I don't understand one bit because I thought S3 was as good as the others.
Then there's the Szechuan sauce BS as mentioned above. So yea, a bunch of toxic and immature kids who make mountains out of mole hills and don't miss a chance to type "Pickle Rick" or "Wubba lubba dub dub" have a bad rep for being shitty fans.
No it doesn't, I still love the show, kinda filled the void that Futurama left.
Been watching Bojack Horseman for the past one week, it's another decent animated show worth watching atm.
