My personal favorite for flawed reasons is Madoka because I was there for the live reactions to the infamous episode and it was magical watching everyone lose their shit. It was also my re-introduction to anime after being shamed out of it for liking sailor moon as a kid.
I love discworld, especially the one about night guardsman.
I avoid horror movies but I’ll check those out.
From what I remember Tucker and Dale is very much a horror comedy, and Cabin in the Woods has a very strong comedy/post modern commentary thing going on. They're both very different from conventional horror movies.
