The idea of repeating one day of your life day after day is such an obvious premise for a movie that anyone could have come up with it. Despite this the 'gimmick" behind Groundhog Day is so rife with storytelling potential that a small subgenre has been created of movie with variants on the Groundhog Day formula such as Happy Death Day and Edge of Tomorrow.
Do you agree? Disagree? What premises for movies made you thank, "Damn why didn't I think of that?"
