Wesley Stenzel’s review published on Letterboxd:
A quintessential redemption arc built around one of the best premises ever. Ramis follows the time-loop concept to all of its logical conclusions and fulfills its full potential. Phil’s progression from confusion to elated selfishness to depression to poignant selflessness happens very naturally, and Ramis and co. take the concept to pretty much every place you’d like to see it go in a two hour time frame. The non-Phil characters aren’t particularly memorable or likable, but they don’t have to be, and the funny, efficient screenplay makes up for it. Seriously, this should be taught in classes on unflashy-yet-effective screenwriting and editing. The wise lack of explanation gives the film a charmingly mysterious conclusion. Overall, a really excellent exploration of ego and loneliness, and a powerful testament to our capacity for goodness.
