The best analogy I can make is that it is like looking at a beautiful painting. It is beautiful to look at and you analyze and pick at it but after awhile you're sort of bored and your mind drifts and you start looking at the time, then you become antsy and want to leave.
Le Reve is just that. There are no thrills, hardly any flash and the comedy is mediocre. However, the show is very beautiful to watch. If compared to any of the Cirque du Soleil shows, Corteo would be the most similar in it's beauty.
