Aside from re-creating two or three minor scenes, Silent Night in no way could be called a true remake of 1984's extremely controversial Silent Night, Deadly Night. Flicks about a killer Santa Claus have existed before and since; if not for the value of a brand-name, this could be just another.

There's a theory about remakes that perhaps Hollywood should stop remaking good movies and instead remake the bad ones, so that they may be improved. The problem with that theory is one runs the risk of the remake being bad, too. Case in point: The Philadelphia Experiment.
