“Centigrade” (** out of four) was a pretty banal melodrama about a married couple (Vincent Piazza and Genesis Rodriguez) who find themselves trapped in their submerged vehicle after a blizzard and struggle to survive amid the frigid temperatures, lack of food and water, and other multiple obstacles. Film is an entirely two-character story which we’ve seen many times before (“Open Water”, “The Road”, etc.) and may have worked better on the stage than as a feature film. Both Piazza and Rodriguez are good and do what they can with underdeveloped roles but this still doesn’t quite make the grade.
