The Sacrifice Game

Group of sadistic young people killing their way into a boarding school for girls just in time for Christmas, trying desperately to summon a demon to become even more powerful. Silly as hell and it doesn't work when it is about torture porn -- every death is the same! (slit throat and let it bleed) --, but the supernatural bits are cool -- too bad they come in the last 35 minutes or so. Oh, and the twist, if there is really one, is suggested way too early, but it actually works.

The Holdovers and this coming out the same year is very synchronized and works as its demonic cousin
