I'm genuinely very happy B.T found himself during wierdmaggedon.
That isn't a joke or an exaggeration for comedy. It genuinely made 12 year old me so happy. ^^
The punching bag character is very counter productive in a show supposedly about embracing oddities, although it's obvious the show stumbled into that message, out of a sense of obligation, when it would more often be petty and mocking in a very 2000s 2010s way.
Gravity Falls would have suuuuuucked if it was an adult show "unrestricted by mushy kid's shit" x[
It's actually obnoxiously judgemental a lot of the time, no better example than the popularity of dipper and stan and their "witty remarks" which is just them being insecure assholes, both when the show is aware of it, and when it isn't.
