Chimp Crazy, like Tiger King before it, is a difficult watch. It follows chimpanzee owners and their almost fanatic loyalty to the primates (one famously breastfed a chimp and raised her as her child), but mostly it trails Tonia Haddix, an animal broker who is obsessed with the 32-year-old chimp and sometime Hollywood star Tonka. I won’t spoil the things she does to save their relationship, but I assure you it’s chilling and outrageous. That said, shock isn’t the only thing Chimp Crazy has going for it. The curious way it’s filmed is surely cause for debate. And the way everyone here—whether that's Haddix, the occasional dangerous chimp, or the near-manipulative director Eric Goode—seems at once manipulative and sympathetic is a feat of its own.

Goode gives her dimension, but Haddix is one unforgettable character.
