New in Town is right. People who never saw the show as it was originally directed probably don't realize that the direction was the real star of the show.
The book and score are mediocre at best, but the ingenious Tommy Tune direction and choreography made it really entertaining. The movie includes none of that.
Remember the Aggie cheerleaders, each strapped to cutouts of two more cheerleaders with pink balloons in their halters, the flashlight choreography of the Melvin Thorpe singers?
The one possible problem is that the show was very transgressive in 1978. Part of the show's charm was prostitution presented as romantic, small town, Americana. Today...?
