I've always wanted to know about the madness that went into making Ren & Stimpy, and that doc was plenty informative. They want to paint creator John K. as a monster, how he was a dictator, but I feel like the end justifies the means. His batshit "storytelling" helped pave the way for better cartoons, but it definitely seemed to alienate him. It also delves into his scandal, though they never mention any specific sexual misconduct. John K does seem like a weird guy, but in that perfectionist-artist type way. At least the doc wasn't completely biased against him, and did feature his take on things quite a bit. I wouldn't hold out hope that any of that team would ever reunite, but it doesn't taint the wish that he would still come back and do more episodes like they announced a few years ago. If you loved that show as much as I did, it's definitely worth a watch.
