Watch Groundhog Day alongside a movie like Home Alone and you'll see that there's a clear mid-90's vibe that runs through both these movies. A lot of the camera shots and conversations are of short-to-medium length and many of the scene transitions use classical music.

There's really nothing about Groundhog Day that breaks the mold as far as production goes, but that's one of the reasons why it's such a good typical example of movie directing back in the mid-1990s.
