Nostalgia Charlie Kauffman has directed yet another masterpiece about life,death and purpose of our existence with a dreamy presentation. This is a movie about a lonely man, who works as a janitor in a rural school and spends his time dreaming about what he could have done. He feels nostalgic about things he hasn't even committed. Musical at the end is pretty much the reality of Jake's life. All the women apart from her mother in this picture are the ones he once saw in different parts of his lifetime and liked,but couldn't interact. To make this clear, when Louisa talks to janitor (Jake) she says he just creeped on her,which is exactly what happened in real life. Another example,after we see her showing Jake's parents some of the paintings she has done,those exact same paintings appear in Jake's room too indicating they are actually what he has drawn in real life. Louisa is just a part of his imagination,as are all the women,he keeps living in those dreams where he even wins a Nobel prize but in reality,he is nothing more than a sad lonely janitor who regrets every second of his life and still confused at an old age about his existence.
