‘Untamed Heart’

By all rights, a movie about a Minneapolis waitress (Marisa Tomei) who finds true love with an orphaned busboy (an impressive Christian Slater) who needs a heart transplant should be a hoot. Although swatches of the 1993 film are as goopy as one might fear, Tomei’s performance keeps the film together. Caroline’s an original because Tomei brings a new-minted freshness to every moment, every gesture. The scenes in the diner, with Caroline gabbing and roughhousing with her best buddy Cindy (the always spunky Rosie Perez), have an easygoing charm that captures the way people can turn their jobs into cabaret. Directed by Tony Bill (KNBC Monday at 9 p.m.).
