Beautifully shot (and set)
With a fair amount of atmosphere, and the acting was solid in my opinion.
All of the technical elements are really well done. It's a really well-made film on a technical level in my opinion.
But I agree with the common complaints: it's too slow, too uneventful and sparse in its story, especially for such a short film. Too many things are underexplained--there are a buncha plot holes, really, which is weird for such a simple story. And it's pretty cliche in a lot of ways, including that especially the one twist is pretty much old hat by now.
At that, though, I liked the twists and felt that they somewhat saved the film, but still it was frustrating overall, because it could have been so much better.
A 6/10 from me.
