2) Observer - The manner in which Mikkelsen, the former Danish gymnast and dancer we chiefly know for his suave villains in 2006’s "Casino Royale" and the NBC series "Hannibal," plays off his largely mute charge is simply extraordinary. (Rating: 88) Read Full Review >

Worst two reviews:
28) The A.V. Club - If the bare-minimum characterizations at first feel like a refreshing alternative to the most modern survival film (think everything from 127 Hours to The Shallows), they eventually betray a movie that maybe—just maybe—doesn’t have a lot of ideas about where to go past the first act. Like its protagonist, it trudges toward an unknown destination out of obligation. (Rating: 58) Read Full Review >
29) The Playlist - The simplicity of the film is commendable, but it’s only in the last act where things finally come together and any kind of visceral thrills arrive far too late. Even Mikkelson’s on-screen talents can’t save an admirable yet stagnant film in dire need of a heartbeat. (Rating: 58) Read Full Review >
