Player Affinity writes: "Do you know who you are? When were you born? What year is it? Well, even if you can’t answer these queries, hopefully you can still read, because Player Affinity will now take you through memory loss tropes in film. Memory loss, mistaken identity and amnesia-themed films are a convenient plot device, a crutch even, when filmmakers are looking for a quick way to materialize some danger, progress the zaniness of a rom-com, or craft a psychological thriller. Unknown, starring Liam Neeson, falls within some common trends in the genre as it finds a man who after awakening from a coma tries to piece together the truth of his immediate past while his entire existence is seemingly stolen from around him."
