This is a very good crime/comedy/horror movie that's very straightforward, but remains well-made and entertaining throughout. It's about a taxidermist stuck in a loveless marriage who gets the idea one day that maybe he can pull off the perfect crime, and be rid of his wife for good. Naturally, things spiral out of control and get very chaotic from there.
There's less horror elements than I was expecting, for a movie with the word "skeleton" in the title. Taxidermy is creepy, and the house that most of the film takes place in looks unsettling, but it's probably more of a pitch-black comedy over anything else.
And as a dark comedy, it works well. The acting's all very good, and the otherwise dark story becomes more entertaining because of the film's interesting, surprisingly comedic tone.
I wasn't in love with the film overall, but for a straightforward, fairly short, darkly comedic crime movie, it worked well. I can imagine that if the Coen Brothers have seen this, they'd be pretty big fans.
