I was walking passed 47th the other day and overheard a few tourists talking about it, and the female tourist kept saying "It's about a friggin truck! A truck!"
I feel like that explains the average tourists view on the show right there. I personally haven't seen it, but I wouldn't turn down the chance to do so at some point.
