Just okay. If you are looking for something to do, this would be good. But as far as horror genre goes, it’s pretty terrible. It had some laughs, though.

Clunky horror in-jokes, like a heavy-handed Scream nod in the name of Winnie's aunt (Isabelle), feel labored, and it's all plagued by the same unevenness that afflicted director Tyler MacIntyre's Tragedy Girls: The gore and the comedy are well-executed, but the timing is off.

As you’d expect, It’s a Wonderful Knife is filled with blood-spattered twists on holiday movie tropes. Unfortunately, there are few surprises and only a handful of genuine scares, and the film suffers from subpar lighting and occasionally clunky editing. It’s a “Knife” in need of some sharpening.

It's A Wonderful Knife might make its points with steel blades, but that doesn't negate the saccharine earnestness that assures this one as a new Christmas horror favorite with a heart three sizes bigger than you'd expect.
