One of my all-time favorite comedies is 1993's GROUNDHOG DAY. I actually had no intention of seeing it but one night when I went to pick up my wife from work she ended up having to work late. With a couple hours to kill, I remember deciding to see a movie at the theater across the street.
And I loved every minute! It's one of those I can watch over and over again and not get tired of it...which I guess is the point.
In fact, someone once suggested that they announce a GROUNDHOG DAY II...and then simply re-release this one! Works!
