Much like Bruce Campbell's documentary "Fanalysis", Tom tries to figure out why are people fans of such franchises.
He interviews Potter co-stars Dan Radcliff and Rupert Grint and the mother of Potter herself, J.K. Rowling of what they think of this Potter obsession.
He visits three Potter superfans in their houses and asks them why they are obsessed with Potter. The first fan said that he was an outcast at school and saw Potter as an escape from reality, the second fan said that she suffered from depression and also needed to break reality and the third fan who was Tom's main target, his superfan, Tina.
Why is 50 something year old Tina a Potter fan? Well, she said she never had any children and sort of saw the kids of Harry Potter as their own. "We've watched you all grow up."
Tom also meets Celebrity autograph hunter Brian Pechar and they try to get autographs with Nick Jonas (which doesn't work) and Rupert (which does). Tom dons a disguise to make him look like Doug Walker's character Chester A. Bum, which fools Rupert.
Finally Tom goes to a convention dressed as the Joker and tries to see why people like to dress up as their favourite characters from media.
Earlier on, he meets William Shatner in Comic-Con and he comes across as arrogant. He certainly lives up to his surname.
I really enjoyed this doc and I hope Tom makes another one soon. He could be the next Morgan Spurlock.
