How does an RBMK nuclear reactor blow up? We spend this extra-long episode of Unfilmable trying to find out, as we watch HBO's Chernobyl miniseries. While not categorized as a work of horror, it's impossible to not be terrified by what is shown. And the way the real-life events are fictionalized here and turned into a narrative pulls not only from horror film, but goes all the way back to Lovecraft and weird fiction more generally. So watch the miniseries if you haven't already, and come listen to us justify why it's one of the best works of horror ever made.
