'Camp X-Ray' debuted earlier this week at the 2014 Sundance Film Festival, and critics have generally positively received the film, with IMDb giving it a score of 8.1.

"Sattler does an impressive job of stitching unpleasant facts about Guantanamo into the narrative - from those tricky Convention semantics to Cole's discovery that the cell lights are never turned off at night," said Amber Wilkinson of the Daily Telegraph.

Rob Nelson of Variety adds, "In a turn that will surprise and impress those who know her only from the "Twilight" films, Stewart is riveting, especially in the final scenes, where Sattler reverses the camera's perspective so that Cole is the one viewed through the window, appearing as a sort of prisoner herself."

Film.com's Will Gross also praises Kristen's portrayal of a Guantanamo Bay officer, he wrote, "'Camp X-Ray' may offer frustratingly little insight into the hazy world of wartime morality, but if nothing else, it suggests that Stewart may escape her own 'Twilight'-shaped prison yet."

However, as always, there were some critics who just couldn't be pleased and Xan Brooks from The Guardian was one of them. He thought the plot of the film was, "So crude and overstretched, it's a wonder [Stewart] didn't attempt to tunnel out before the credits rolled."

'Camp X-Ray' debuted at the Sundance Film Festival on January 17th 2014.
