I think the name of the one coming out this year is "The Darkness". I agree that horror movies shouldn't be relase on christmas day. However, it's not like they can release a jolly christmas story on christmas day; once people actually started to see it, Christmas would be over.
I really don't think movies like this are the "death and distruction" of the christmas spirit because the people who go and see these kinds of movies on Christmas either don't celebrate or don't have the spirit to begin with (I might be generalizing there). The number of times I watch TV, the amount of holiday commercials around this time of year FAR outways the number of times I see scary, blood and guts previews. Most of the time now when I see previews like this, they are for video games anyway.
