Banshees of Insherin is one of the funniest things I’ve ever seen. The understatedness is critical to the humor and story; it’s a juxtaposition of boring people in a boring town and the batshit plots that develop.
Other recent greats are maybe Poor Things, Challengers, and Conclave.
You wouldn’t mistake any for Shawshank, but that’s ok, it’s 30 years later. Shawshank is also qualitatively different from great movies in the mid 1960’s, like Dr. Strangelove or The Graduate.
