Glad you posted this information. Have never seen the play nor the movie and it sounds like I may be missing something. I thought it may have been "Too Loud" for my taste, but maybe I was wrong.
I agree Mamma Mia is a very good musical.
However, I thought the following three current playing great musicals wer even better in following order:
1. Book of Mormon
2. Jersey Boys
Saw the Jersey Boys last time there. What a trip down memory lane! Will have to see Book of Mormon and Wicked if still there next trip.
NYC is a great place to see the theatre. We always go to the ticket center in Times Square and usually take in 3 plays in a week with the half price tickets there!
We did see Mama Mia....it was very good. Would recommend it also.
