“Hometown Hero” (*1/2 out of four) was a saccharine love story about a divorce mediator (Brooke Nevin) having to care for a client’s dog whom she has to take to a local vet (Jake Sandvig) and the two soon fall in love and thaw one another’s hearts. The kind of movie that gives the word “contrivance” a bad name; romantic comedy fans may like it but it’s awfully gooey and cheesy. You may want to watch “Must Love Dogs” instead.
