After a time loop lasting several days, it is finally February 3rd and thus Phil's shadow (both the groundhog and the protagonist) is no longer relevant; the dark part of Connors' former self is no longer following him around wherever he goes, and he has learned a valuable lesson about courtesy and kindness. What a beautiful film. This is what I call a comedy with lots and lots of heart. Rest peacefully, Harold Ramis... you were an excellent filmmaker, but above all else, an excellent human being with valuable advice to share with all others.
