...

On the review aggregator website Rotten Tomatoes, 55% of 207 critics' reviews are positive, with an average rating of 5.8/10. The website's consensus reads: "Liam Neeson elevates the proceedings considerably, but Unknown is ultimately too derivative – and implausible – to take advantage of its intriguing premise."[14] ... 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."[17] Justin Chang of Variety called it "an emotionally and psychologically threadbare exercise".
