Structure of Eternal Sunshine of the Spotless Mind

The structure of this film was very different because it went backwards, but mid way went forwards and they ended where they started. I liked i because it required a lot of thought within the viewers mind, but it wasn't impossible to figure out. We were given clues of where the film is by Clementines hair and different memories they had together. The story is complicated so if it was done chronologically it would have taken away from the complexity of the story. This movie is kind of like Citizen Kane because we are told the ending first but the rest of the story is told afterward in a bazaar sequence.
