Christopher Nolan's memento has blown critics away, been nominated for Oscars and left all audiences scratching their heads and ready to watch it again. what makes Memento so unique and different is its backward plot structure. starting form the end of the film and switching in and out out of sequence it gives the the audience of being in the main character's point of view.
The basic plot to this very complicated and confusing story is based upon Leonard Shelby, and insurance investor who looses his short-time memory due to a brain trauma He is unable to create new memories, and only relies on the memories he had before the accident. His wife was killed by a robber, and despite his state he wants to track down the murderer and kill him. He uses photographs and tattoos on his body to make himself remember the important facts.
now imagine that plot, but all in the wrong order, surprises thrown in, character's made to confuse the storyline and Guy Pearce topless 89% of the film. And you have Memento.
It's repeated editing help you understand and keep up with the storyline and the characters. It's one of those films you can defiantly watch again and again, and like Richard Kelly's Donnie Darko, you will end up with a different conclusion every time. If you are fond of films like Brick or Donnie Darko than memento is definitely for you. An outstanding, entertaining and gripping thriller, A must see.
