I have recommended the movie, "The Unknown", because of its excellent direction. The movie keeps one spellbound. It captures the audience's attention and emotion, when "Martin"s memory is partially impaired.
Humans live from memory. We learn our language and remember the right words to even communicate with others when we grow up. What if we couldn't remember our words? This was not the case in "The Unknown", as his memory of important emotional facts was intact, but some of the other facts were forgotten due to an accident. Due to the "missing links", he is living in "limbo" land, not able to understand many things happening to him. How does he interpret them?
Whenever humans don't have a grasp on reality, such that they can find security, they find themselves anxious. Anxiety is the state of "not knowing", or fearing that which "might come". Why would this anxiety have any hold on a human being? When experiences continue to confound and there is no rationale for what is happening, humans become anxious about their futures. A "state of peace" or psychologial security is the result of learning about "cause and effects". Behaviors are conditioned by "causes and effects". But, "sometimes the "causes and effects" are not straightforward "laws of nature". These have damaging effects on the psyche. Post Traumatic Stress Disorder could be the result and might have a disorienting effect on the personality.
Humans must have some sense of control about thier life to maintain a sense of dignity and personal orientation about "reality" itself. "The Unknown" brought to light what it is like to experience a dis-orienting experience where 'life doesn't make sense. The Unknown gave a sense of what life would be like if one lost partial memory and had to "live with it".
Memory or the brain's recording or experience is not the "whole story". Memories have to be itnerpreted to be meaningful, but when some information is "lost" and one is left to interpret without all the 'facts", then what? This made for a great movie.
Go see it. You won't be disappointed!
