I like to think its kind of a coping mechanism with some people around him. Specially in this current era of cartoons, whenever a bad episode comes out it tends to be followed by a stream of subpar episode while don't reignite the fire enough.
Happened with Gravity Falls, happened with Adventure Time, happened with Regular Show, SU, Star vs TFOE....
Even if any show recovers eventually, which some have, people on /co/ has suffered too much burnout to lower its guard again.
Luckily it seems everytime OK KO has a miss, it is followed by another hit episode, so the momentum doesn't go away fully. Of course ever show has a slump so I want to see what'll be the reaction then.
