It's about some upper middle class kid who feels all alienated and has some problems with getting along with people and has schizophrenia. When I was 16 I was a Rolling Stones fan and thought Beatles fans were pussies so I probably would have identified with his angst. But I'm not 16 anymore and I got over it.
You'll like it if you're 16 and feel like an outcast. You'll identify with him. It's pretty dark though.
