Alright, I'm fully onboard once not-Will Sasso gets running around with a legless man tied to his back, smashing cannibal cops and grannies in the face with an iron. It just took too long to get to that point. The rest of this... ehh. It really needed that extra bit of reckless abandon throughout.
The cannibal family gets revealed like 15 minutes in, and the whole thing coasts for the next hour. It just turns into corny "isn't this funny, we act so normal but we're totally just cannibals! lol" kinda jokes. It's too much for me. Would've been a killer short, or as part of a Christmas anthology. Oh well.
It's a Wonderful Knife... no
White Meat Christmas... no
Christmas with the Cannibals... ehh
Jingle all the Flay... terrible, just terrible
I guess Mercy Christmas isn't the worst name, it's certainly better than anything I could come up with!
