I'm not completely certain why this needed to be a Cirque du Soleil show. The music is great; it's the Beatles after all. The costuming is trippy and some of the stunts are spectacular.
That being said, this is really a series of set piece stunts done without much narrative linkage one after another to a Beatles soundtrack. Really, any troupe of acrobats could do that.
It's not like Ka. Only Cirque du Soleil could do Ka. All the athleticism, stunts and choreography is integral to the narrative and the telling of the story.
It's still good and worth seeing especially if you get Tix For Tonight, but it's the weakest of the Cirque shows in Vegas. Best seats are the last four or five rows high in the "bowl" or low in the balcony.
