The rictus that spreads across the faces of those who are about to kill or be killed is probably the scariest thing about Smile, a routine horror movie that has not much going for it other than some committed performances, particularly by Sosie Bacon as the psychiatrist being driven mad by a supernatural being. Horror movie fans accepted it despite a phony premise and some deep inconsistencies in the plotting, so it spawned the inevitable Smile 2, from the same writer-director, Parker Finn, in 2024. You know who you are and whether you want to watch it.
