Quick Review: Its 'angry kid wants Santa killed' premise may sound fun on paper, but execution-wise, there is nothing enjoyable in "Fatman" - a grim, unimaginative, humorless and overly realistic genre mash-up that take itself way too seriously to work as a black comedy, but at the same time it's too absurd to be a worthy crime action, and not even the great Gibson feels comfortable starring in this bleak, joyless bummer of a non- fantasy holiday flick as the shabby and miserable Mr.Claus.
