I wasn't too keen on that ep' either. Not because I'm a "gun enthusiast," but because it kinda strawmanned, was was too heavy-handed, biased, and kinda had an almost propoganda-like pro-politician/burocracy message at the end.
...(And I'm kinda an "old-timey liberal" in the sense I don't trust politicians or burocracy 100%, regardless what side they're on.)
Only thing I liked about O.K. K.O. was maybe it's homages to retro cartoons/video games, having Jim Cummings, some of it's character designs, and it's crossovers. Especially, the Sonic one.
Other then that, I couldn't really get into it.
The episode where the main characters turn into "furries" was kinda funny though, and did a good job at poking fun at the idea of having anthro personas, without being mean, or insulting about it.
Pffft... Anthro personas. What kinda weirdoes have those? :P
