Fantastic watch, will watch again, and do recommend.
Bill Murray carries this time-shift-loop adventure in hilarious form. The writing is excellent with a "redeemable protagonist" trope mixed in.
The movie is creative with it's divergent time lines and even manages to maintain proper story arcs as Phil continues to loop.
The supporting cast is wonderful in each of their roles, and manage to do repeat acting excellently.
This was a popularizing (if not a birth) to a genre, everyone should have watched this movie at some point.
