“It’s A Wondeful Knife” (** out of four) was a meager horror thriller about a young woman (Jane Widdop) who saves her town from a psychotic killer but has numerous ensuing problems with anxiety and PTSD and upon the holidays finds herself in a parallel universe in which she realizes how life without her would have been much worse even as blod and gore starts piling up again. Promising beginning soon gives way as film becomes tiresome and silly especially the finale involving the town mayor (Justin Long). Clever title though.
