I loved this particular show by Cirque du Soleil. It was entirely different than "O" and "Le Reve". The music was really fun, and there was so much going on. My only complaint was that I couldn't take it all in fast enough.
I have recommended this show to a handful of people. They all loved it. This show will likely continue in Las Vegas for many years to come, but I would catch it sooner rather than later just to be safe.
As for seats, we sat up close which was great. Looking around the auditorium, it was hard to imagine that any of the seats were short of spectacular. Just go!
