Who watches it? I make no secret of the fact I think it's probably the best TV show ever made. It combines virtually every well-known genre imaginable, and once you explore some of the metaphor and allegory used in it, it starts to become more than just a TV show.
Not only that, but it's also an utterly compelling watch. Every time you get a question answered, you end up asking ten more.
I'll gush more about it once I know there are others around who can sympathise.
