How bad is it? Waste of time.
Should you see it? No.
Udo Kier and David Carradine sleepwalk through this film, while the rest of the cast overact. On Christmas Eve (the first cliche of thousands), a killer tracks a witness to an office building that just happens to be in a rolling blackout. The phones also just happen not to work. The plot is awful, the dialogue worse, the soundtrack intrusive and the effects mediocre (it looks like a TV movie budget). There's a kevlar vest that only works when the plot requires it to. It's slow and doesn't even come to a satisfying end.
