Mostly style, and little substance, but it worked for me. Cynthia Erivo is the standout of an extremely talented ensemble.
This review may contain spoilers. I can handle the truth.
An effective thriller, and a pretty good allegory for my feelings about this country: eventually I will grow too tired to fight against the pod people, and I will be unable to stop this place from turning to shit.
Also, this is the most disturbing PG-rated film ever.
