Search Party (2016)

The odd one out, on purpose. Alia Shawkat's aimless Dory learns that Chantal Witherbottom, a college acquaintance she barely knew, has disappeared, and she throws herself into finding her, dragging along her boyfriend and two friends who are mostly interested in themselves. It is a dark comedy, and the joke is how much the search becomes about the searchers, which makes it a sharp counterpoint to the earnest shows on this list. Season one is the disappearance story and works as a complete arc. The show then ran five seasons in total, first on TBS and then on HBO Max, getting stranger as it went.
