Probably Late Night With The Devil. I haven’t had a chance to watch it yet but I want to.

Movie is definitely top tier, I also love the novella. Different Seasons is what I point to when people dismiss stephen king. Shawshank Redemption, Stand By Me, and (while not on the level as the other two) Apt Pupil all in the same collection. But to each their own; pretty sure the final story is trash though haha.
