A classy and finely crafted thriller that's part Twilight Zone, part changeling folklore. It takes a while to get going, but once it does, the evocative mood and excellent directing make up for it. My one complaint is the main characters, who are such insufferable shitheels that I couldn't bring myself to care about them. In a horror thriller like this, you'd need at least one person to care about even if it's remotely. Here, the lead duo is in solid contention for Worst People Ever, and even digging at the bottom of my well of empathy proved fruitless.
