Fan Fiction & Art

Do you read fan fiction? If so, comment below and tell me what you think of it. I tend to be a purist and I think I would just be annoyed by it, so I've never read any. Fan fiction, on first glance, seems to be one of two things. Either it's an homage without any intent to publish, or it's an amateur's attempt to ride the coattails of someone else's success as a way of breaking into writing. Either way, I just don't find myself interested.
