I never liked circus. It was mildly interesting in tv or movies. The one time that I went to a show, I was lucky enough to be far from the action: a lion sprayed the two front rows. The smell was everywhere, everything had a sad vibe, even (maybe specially) the clowns. Only trapeze artists saved the evening for me.
Cirque du Soleil was an entirely different matter. Everything was shiny, cool, happy. My son had a great time. I had a great time. Sad to see them close. Hope they can come back to life somehow.
