There was a movie don't remember but I think it was late 80s early 90s about a monster Santa one the at the end the daughter in the family was sitting the house and the mom and dad say there is no such thing as Santa and they get sucked out from the house and they die and the little girl say I told you there was a and the boy tell her don't say it and that's the end of the movie the Santa was like a demon Santa I don't know if I seen it on a twilight zone or a movie but that's all I remember can some one help me with this one

It could be "Silent Night Deadly Night"

No its not that one the movie was a monster santa not human I seen the silent night one and that's a human the one I was talking about was a monster

It sounds like Tales From the Darkside - "Seasons of Belief".

I actually just watched it the other day. The parents tell the kids about something called the "grither" on christmas eve. If they say the name too many times, it comes to get them. I guess it's kind of like an evil santa - but it kills the parents after they say there is no such thing.

There is an episode of supernatural I think in season 3 like that
