As a man-child, I
had to open my gift early....
What a surprise this is! 
An excellent horror movie, definitely makes my Best Of The Year New Horror movie list.
Cleverly shot, with particular emphasis on Christmas colors...somebody was actually thinking here.

Not once do you forget what season it is.
PQ of the BD is excellent, with great shadow detail.
AQ is fine.
There is only one problem that jumped out at me: Malcom McDowell.
He is incredibly bad here....completely miscast.
Although some of his dialog isn't the greatest, he is just horrid...it really is embarrassing.
If you can look past the McDowell Mess, this movie is good fun on every level.
