I was able to watch only a few episodes of this series when it appeared in 2016. The humor was too sophomoric for my tastes (but then most on TV is). Now I wish I had watched all of the episodes (and that there had been more).
"BrainDead is an American political satire science fiction[1][2][3] comedy-drama television series created by Robert and Michelle King.[4] The series stars Mary Elizabeth Winstead as Laurel Healy, a documentary film-maker who takes a job working for her brother Luke (Danny Pino), a U.S. Senator, when the funding for her latest film falls through. Assigned as his new constituency caseworker, she discovers that Washington, D.C. has been invaded by extraterrestrial insects which are eating the brains and taking control of people, including members of Congress and their staffers. Much of the internal comedy of the series was that, in the altered reality of Washington DC politics, only a few people noticed.
CBS announced a 13-episode straight-to-series order on July 22, 2015. The show premiered on June 13, 2016. After four episodes, the show moved from its Monday time slot to Sundays to make room for the network's coverage of the Republican and Democratic National Conventions.[5] The show had a planned four-season arc, which would have seen the bugs then invade Wall Street, Silicon Valley and Hollywood,[6] but on October 17, 2016, CBS cancelled the series after one season.[7]" -- Wikipedia
Watching events play out these past few weeks, I think the show was prescient...
