There’s a comfort-food satisfaction about a rom-com – if the actors in it are decent enough. Renee Zellweger and Harry Connick Jr. are decent enough, and “New in Town” (2009) is like a sweet bowl of tapioca. Supporting cast Siobhan Fallon Hogan and J.K. Simmons are more than decent enough and what is basically an empty-calories, color-by-numbers story (career-minded female executive is fish out of water at rural Minnesota food processing plant, what with the townsfolk’s Flyover Country ways and all, but everybody learns a little something about themselves, yada, yada, yada). Like scrapbooking and other hobbies, it’s time well wasted.
