I've seen Penn & Teller in Vegas many times in many places. The first time was kind of magical. The second time a year later the show hadn't changed a bit. At the end of the show I made a card that said "I promise to have a new show next year" and palmed the text.. During the autograph session at the end of the show Penn signed it.. Then read it! I thought it was kind of funny.
This years show indeed had some new acts that were great.. But at the same time had some of the same tired stuff from many years past. The stagecraft has got a bit slow and amateurish.. Two of the people we brought that don't know P&T really didn't get the slow meanderings of most of the show.
The whole TSA thing was a bust for me as well. Showing people how to get a knife through security at airports is best for Showtime's Bullshit not for an entertainment show in Las Vegas.
I think it's time for P&T to spend some time, talent and money and make a show worth seeing for 100.00 a pop.
