“Big Sky” really isn’t that bad a picture until it decides to start getting surreal and existentialist. You figure a movie about survival would keep it simple, but Jorge Michael Grau tries to play the narrative with much more depth. That said, “Big Sky” is a perfectly fine thriller with a solid cast. It kept me invested, and it’s always fun to see child stars evolve in to more unique performers. This is one of the few roles Bella Thorne has taken on in her adult career where she’s not a shrew, and she plays the heroine very well.
