I loved their act when I saw it a couple of years ago, and I'm glad I decided to check them out again last night.
The show has changed a little bit over the years. Whereas before they'd painstakingly explain every trick except for the finale, now some of their bits are more commentary & comedy than magic, and there's a couple things where everyone is in on the bit except for the person plucked from the audience. In other words, now you have to really pay attention to truly appreciate the show.
This is easily my favorite show in Vegas. They've been at the Rio for almost 10 years and I hope they keep it going. It was great to see that they've kept it fresh over time. One thing that hasn't changed is the meet and greet in the theater lobby where both will sign autographs, shake hands, and pose for photos until the last guest walks out the door.
