Wow, I couldn't disagree more.
I guess we get different things from the show. Its lack of conventional storytelling and characterization is what appeals to me. The characters are cyphers - it's not who they are, it's the roles they're playing in this week's con. The plot is all. The suspense comes, not from the characters being in jeopardy, but in seeing how it's going to come together - how that daft gadget Barney demonstrated in the teaser is going to come into play - how the villain is sucked into the con. Like watching a jigsaw puzzle being put together. Obviously I wouldn't want all shows to be like this. This is the exception.
