This review contains spoilers for “Happy Death Day” and “Happy Death Day 2U.”. It’s birthday season, Wesleyan. 9 of the 10 most common birthdays take place this month. I’m sure most of us know at least three or four people who celebrate their birth in September, and every weekend comes with another set of birthday pre-games, parties, and picnics. Yesterday was someone’s birthday, tomorrow will be too, and the day after that, and again and again, and so on and so on. You could say it almost feels as though the days are…repeating.
