Maybe I'm just too thick to understand what really happened. Like for instance, why was the neighbor digging in the first place? He didn't seem a bit like a fella coerced into shoveling by any unseen presence. So then how did the killer know to return the shovel?
One might guess he was lurking nearby while the husband chatted that fateful night, but there's no evidence the filmmaker cared to acknowledge either plot hole.
IMO the best mysteries oughta have a "tell" somewhere along the way, a reason why, as the credits roll, the reader / viewer can exclaim.. "Ah hah, I shoulda coulda woulda guessed." Not here.
