It would be interesting if they did the "circus" thing, although like you Maddie, I'd probably spend most of the time comparing it unfavorably to
Carnivale, haha (one of my fave shows ever, despite its glacial pacing).
Heroes also attempted to do a circus thing in its 4th season, and yeah...didn't turn out so well. Coincidentally one of the actors who played a minor character on
Carnivale was the "villain" of the circus season on
Heroes...I can never remember the actor's real name, so I just call him "Tommy Doolan!"
