Didn't go in with much of any expectations and didn't watch the trailer, which I think is the way to approach this taut little suspense thriller that ends up feeling like a two-person play when the two "old friends" get back together.
Loathe to provide any sort of details, other than wonderful performances, tense AF, thought provoking, at times traumatic, thought experimenty...this movie will make you think, feel, and possibly even shout at your TV at times.
Going to have a things-going-wrong-in-the-house nightmare about wasp nests in the smoke alarm.
