If you have never been to a broadway play or another cirque show then its probably better, but it was just average. I love the Beatles, but the show really didn't make sense and not till the 3-4 song I realized that there is no theme. They just play different Beatles songs and have cast members in 60's garb dancing around and doing the occasional trapeze act or Cirque like acrobatics.
It is more equivalent to a Broadway show with a few really cool acts. Lets just say that 3 stars is still a good review, but not over the top. I would say to see it if you like the Beatles. If not a Beatle fan I would say to skip it and see another Cirque show like KA, O, or Mystere.
