The site's consensus reads: "Liam Neeson elevates the proceedings considerably, but Unknown is ultimately too derivative – and implausible – to take advantage of its intriguing premise."^[12] Metacritic gives the film a 56/100 based on 38 reviews.^[13] Richard Roeper gave the film a B+ and wrote, "At times, Unknown stretches plausibility to the near breaking point, but it's so well paced and the performances are so strong and most of the questions are ultimately answered. This is a very solid thriller."^[14] Justin Chang of Variety called it "an emotionally and psychologically threadbare exercise".^[15] Overall, Unknown was a strong box office hit and scored a number one opening at its first week of release. 13.2 million tickets were sold in 29 territories.^[16]
