I guess I expected more out of the Las Vegas show. I had seen BMG when they toured through San Diego last year and really enjoyed their Rock Concert themed show. It was very original and had a lot of fun audience participation.
And although a small element of that show was incorporated into the Vegas show, it just didn't have the same appeal to me. I found things to move pretty slowly. I would say that the fact that they don't talk made things feel like they were going slowly, but they don't talk in Stomp, and that seemed pretty fast paced.
I definitely like the lighting and the band kicks ass. The special effects for the most part are pretty cool, and it can be hilarious when they bring the right audience member up to help with a scene (or a disaster if they get someone who just isn't into it).
So, overall I give it an "ehh". Fun, but not my first choice of shows on the Strip. I will probably go see them again when I hear that they've updated their content, but for now am content to try other shows.
TIP: Come in late to the show. I dare you! You'll see why...
