“The Christmas House” (** out of four) was a synthetic Hallmark holiday concoction about two parents (Treat Williams and Sharon Lawrence) who have their two now-grown children (Robert Buckley and Jonathan Bennett) home for Christmas and they all divulge various personal and financial secrets that all result in them growing stronger as a family unit. Typical Hallmark production is harmless but bland with endless holiday cliches and plot points. This made history as the first Hallmark film to feature a gay couple but it has little distinction beyond that.
