I saw CorteoIn Montréal when the show was still only a few days old, so you might see something a bit different ( since Cirque du Soleil is from my city Montréal , it both a blessing and a curse: we see the show first , but most often the show evolves and we nerver get to see the "final product!)( Oh , and there world headquarters are just a few steets from us , with the Montréal circus school and a theater completely dedicated to circus show, la Tohue !)
Any way , Corteo is among my favorite Cirque shows. It's look is more "comedia del arte" It feels like an Italian movie from the 20's. The "story" is that of a clown who is on his death bed and is tranported in a feliniesque world. The caracteres look more "real" than in other shows. It's visuals are much more poetic for me , since they are more set in "reality" ( angels bringning our clown flying in his bed , trapeze artist doing there thing in giant crystal chandeliers etc.) I think you will like it, it was amazing
