Ghost World is a brilliant film in my opinion. Why? Just look at the message board and the comments on this website. It's amazing how much people have taken from this movie, especially a relatively lesser known one.
When I first watched this movie, it was a revelation. It was just that good of a movie. The characters, the story, the location all of it was just perfect.
Many people have related to this movie because of its "coming-of-age" or "just out of high school" aspect, and they are true in describing this movie in those terms. But what I really thought was great was how this movie, to me, was about the search for something meaningful and more importantly for Enid, something "real", especially more so in our often contrived and plastic modern world.
That's where "Ghost World" comes in. It is described as so because if you look at the setting of the movie, you can not really tell where in the United States it takes place in. It could be virtually any one of the suburban areas that has sprung up in the past couple of decades. It's true that there is a great deal of comfort and leisure, but at the same time there is a lack of soul. Its not the big city, where they try to emulate its culture and activities, nor the small town, where they try to emulate its sense of tranquility and community, but rather a facade of both, ending up being none. No one is truly happy, yet everyone puts a smile on, and that is what really bothers Enid, I believe. Its a world where sterile hip-hop music is used to celebrate a high school graduation, authentic 50s diners are anything but, and a white "blues" band sing about picking cotton all day long for the man. All contrived, all far removed from its source, all as real as a slushie from the Sidewinder food store.
After all why is she attracted to Seymour? I don't think because he's the dorky record collector with a sour outlook on life, but because he is honest about it. He's not a stuffy collector who claims to know everything, but a guy with a passion for something, even if it isn't something "cool". Even with the Coon Chicken incident you can see that its sincerity that Enid is searching for. Enid is not a racist but she picks the Coon Chicken ad for her art project because it reflects how little society has have not changed, even if it whitewashed itself. Like Seymour said people still hate each other but they hide it better.
Rebecca on the other hand seems to have accepted that society and life at large kinda sucks, so she "sells out" by working at the coffee shop, which is an obvious Starbuck's knock off. But in my opinion, she just realized that she can't change the world and how it is, so she goes on a different road from Enid's. A scene which highlights this is when she shows a liking for brightly colored glasses for her new apartment, while Enid gawks at her for being overtly excited for cups. But who's to say that Rebecca is wrong for liking those cups? How is it different from Seymour's fascination of 75s? Rebecca may have changed some throughout the movie, but at her core she remains to be the cynical and independent person that she is.
Finally, Enid goes away from it all, fulfilling her desire to one day to disappear from it all, because it seems that she can not rely on anyone, not even Norman the bus bench guy. Rebecca is working most of the time, her father is marrying the person she dreads (showing a disinterest or plain aloofness in Enid's life), her art teacher is a talentless hack who doesn't really care for her (or any of her students really, even though she pretends to) since she didn't fight for her after the art show debacle and Seymour disappointed her twice. First by dating a person whom he knows is not his type, yet he conforms to her (literally, just look at those tight jeans she bought him!) and secondly becoming overtly renewed in his relationship with Enid only after a night where Enid and Seymour took their relationship to bed(with a help of a bottle of champagne.
Did Enid commit suicide in the end? Personally I don't think so, it would be such a surrealistic end to a story that is steeped in realism, but that is another reason why Ghost World is such a great movie. There is such an open space for interpretation and such depth that one can talk about it for hours, discussing about it and getting more out it with every viewing of the movie. There's a whole lot more than what I just wrote about, but I don't want to bore you with my interpretation, and there are other things in the movie that other people see in it that I might have missed or disagree with.
But thats a mark of a good movie. Just look at the message board for yourself.
