Yes, there are several other threads on this, not to mention the copious amounts of awards and glowing reviews to reference.
Personally though, to beat an already loved horse to death, I saw it a few months back and thought it was brilliant, inspiring and completely magical. I'd put it around on par with Book of Mormon in terms of quality. The one worry I have is the translation of the British-isms of the show to the US- whether they will transpose the show entirely (ala the film version) or keep it as is and get rid of the more specific nation references (ala Billy Elliot). It does have a few odd or weak points, including one of the most random and odd endings I can think of in recent musical history, but the show as a whole is a beautiful and hilarious capture of childhood storytelling. 'When I Grow Up' is one of the simplest, purest moments I've ever seen onstage, and also one of the most memorable and beautiful.
