Unknown is a well-paced thriller that manages to keep its intensity throughout its close to two hours runtime. It enjoys solid performances from a confident cast directed by Jaume Collet-Serra, and led by Liam Neeson, Diane Kruger, January Jones, Aidan Quinn, Bruno Ganz and Frank Langella. Some plot elements suffer from credibility and the plot is overall somewhat expected, despite a nice twist. Yet if you go with low expectations, as I did, you will not be disappointed.
