Happy Death Day (2017): The pitch seems so obvious, you can’t help but wonder how a film that is ‘Groundhog Day’ meets slasher movie didn’t already exist. On her birthday, a supremely selfish college student wakes up in a stranger’s bed, only to be murdered by the end of the night ... at which point, she wakes up and repeats the day, which perpetually ends in her death. The movie has all the jump scares and deep mystery you might expect from such a premise, but the real draw is the overarching humor and sweetness as she and the stranger begin navigating this bizarre loop together, and she realizes that maybe there’s still time for self-improvement. (That the same premise works again in the sequel “Happy Death Day 2 U” underscores how successful the film proves to be.)
