It's so close to home, it's uncomfortable on occasion but all the better for it.
If you're a sci-fi geek but are self aware enough to understand that your detailed knowledge of the Liberator in Blakes 7 is never to be exposed in polite society, this is for you.
If you've ever been to San Diego Comic-con or LA Who Convention but would never dream of getting involved in Cosplay or actually asking any of the guests on a panel a question because you are aware they are jobbing actors, who have no interest, knowledge or indeed, understanding of the significance of the universe in which they act, then this is for you.
Enjoy.
