I actually liked this a lot. It feels a little like an extended Black Mirror episode, but it's pretty intense and entertaining. It also has its fair share of hilarious moments. Peter Dinklage and Elle Fanning both have a really authentic chemistry with one another, and the whole thing is gorgeous to look at. Reed Morano does a great job at portraying how isolated these two characters are. It takes a twist in the third act that I felt brought things down a bit, but overall this was one of the stronger movies at Sundance this year. B+
