Obviously, with Cirque du Soleil, you're going to get incredible talent, mind-blowing acrobatics, sets, music. This show has the whole cannoli. Very impressive.
That said, I was just a little disappointed with O. Maybe I set my expectations too high. I found it to be a bit flat. At times, I was even bored.
I know its unfair to compare it with Love as they're just too different. However, now that I've seen both, Love is a far more entertaining show.
