This show was fantastic. Penn and Teller go above and beyond a simple magic show to provide a time of entertainment and wonder. Their showmanship is great, their material is awesome and their magic is superb. They are truly masters of their craft. Every trick they performed was amazing and blew my mind. What's also great is that they sit outside the exits after the show for a free meet and greet with anyone willing to wait in the massive lines for pictures, autographs and more. Not something I care for, but it's great that they do it free of charge.
My only complains were that my seats weren't that great so it was a little hard to see some things, but that just means next time I'll be paying extra for the really good seats. I recommend anyone else do the same unless you bring binoculars or something. It's watchable from the upper levels, but the experience would be way better being more close. The other small issue I had was Penn and Teller pushing a minor political agenda. It wasn't very blatant or forceful but was definitely detectable. It's not something I really mind, but I think there are definitely people that care so I wanted to note it.
No matter what, go see this show if you're in Vegas!
