There are no bad seats in this theater. At first, you may be concerned about the curtains blocking your view but they don't as they are removed for the most parts of the show and are only there when they need to project something.
Although you don't need to be a Beatles fan or know their music particularly well, I think it helps greatly in the entertainment and enjoyment factor. It pushes it over the top for me. I love the Beatles. Thanks to my parents listening to them incessantly, it was hard not to hear their catchy tunes as a child.
I recognized all but a couple of the songs played and for the ones I didn't I wasn't as pumped compared to the ones I knew.
This isn't the first Cirque show I've been to but there were less amazing acrobats and more interpretative dance in my humble opinion. If you are looking to be wowed by acrobats then this is probably the least "Cirque" one for you. The best part for that I can recall is the skating part where they do some nice tricks.
If you want to feel good and enjoy the show as they sing the song at the end, then this is the show to see.
You won't be disappointed. Unless you are a sulk!
