ROBERT TRACINSKI: Twenty-five years ago, ‘Groundhog Day’ seemed like just a light screwball comedy. It has since been accepted as a beloved classic with unexpected depths. “‘Groundhog Day,’ a seemingly light and whimsical 1993 comedy from director Harold Ramis, is 25 years old this year, and the film has had an interesting life. It debuted to generally positive but not reverential reviews, yet has since been accepted as a beloved classic with unexpected depths. The general response was summed up when Roger Ebert upgraded his review 12 years later from three stars to four. It seems he only came to appreciate it after repeated viewings—which, given the film’s premise, is kind of amusing.”
