Rejoice, parents: you’ll soon have a new Christmas movie to add to your family’s holiday rotation. If your family was anything like my own, you probably grew tired of placating screaming nieces and nephews with the same ratty DVD copies of A Christmas Story, Elf, or Home Alone. That makes any new holiday movie — regardless of quality — a welcome change of pace. Arthur Christmas? Fine. Rise of the Guardians? It’ll do in a pinch. Rare Exports: A Christmas Tale? Maybe save that one for the time in the evening when the uncles break out the adults-only eggnog. But a Melissa McCarthy Christmas comedy? That could be quite a boon for tired family members everywhere.
