I personally think that YF wasn't half as bad as it was cracked up to be. The reviews in NY were god awful and so we went with very low expectations, but perhaps because we expected so little we found the show to be quite fun. Follies it wasn't, nor South Pacific either, but it was entertaining in its own way.
Interestingly, local critics of the national tour gave it much better reviews than the NY critics (not all, but the majority.) Some even loved it, scaled down sets and all.
