BrainDead (2016)

A documentary-maker working in Washington discovers that an infestation offers a very literal explanation for political behaviour. The 2016 comic thriller turns institutional dysfunction into science-fiction grotesquerie, with musical recaps among its stranger pleasures. Mary Elizabeth Winstead gives the investigation a useful outsider's perspective. Its satire is very much of its election-era moment, but the collision of official procedure and ridiculous menace fits Fallout's comic distrust of authority.
