It's definitely not the best show out there but I thought it was lovely, I had a wonderful time. I may be biased because I adore the movie and the character of Mary Poppins in general. It was a big part of my childhood so it brought back so many sweet memories.
The sets are really impressive but I think it all comes down to who's playing Mary. We saw it twice and got an understudy the second time, that kind of killed it a bit for me but when we got Laura Michelle Kelly I really enjoyed it, she's a great Mary.
