At the end there is a great scene when the last memory is being erased and the memory (and literally the setting of the beach house) is falling apart. Joel realizes that he wants to stop everything and hold on to Clementine and these memories so he decides to try hide away these small fragments of memories left so he can remember them when he awakes from the procedure. A series of dark images begin to flash that symbolize snippets of his memories with details like sand from the beach entering into a different unrelated memory. Finally the movie ends with both of them finding out about the company and the procedure. They decide to give their relationship another shot even if it could end the same exact way. The last shots of the movie are the same shot played over and over as the movie goes to white perhaps symbolizing that the procedure was exercised again and again. Joel and Clementine are now in a state of constantly repeating their relationship like in a circle that never stops.
This movie is a very complicated yet smart film that cannot easily be summed up in one blog post. The production team even makes it easier on the audience of keeping track of the timelines, of what is a memory versus real life, and when the moment occurred in their relationship by the color of Clementine’s hair. This hair goes from blue, orange, red, green, and brown. If you have not seen this film go out and watch it. I promise it will be a movie and a memory you will never forget.
