I’m Thinking of Ending Things begins as a sort of moody couple’s road trip, in which Jake (Jesse Plemons) and his girlfriend (Jessie Buckley) drive out to his (slightly haunted) childhood home for her to meet his parents (David Thewlis and Toni Collette). On the way there, the sense slowly builds that things aren’t quite what they seem; upon arrival, the pair are thrust in directions that bend the laws of reality, memory, and love.
