I'm at a disadvantage because I saw the original production and adored it from top to bottom. I was disheartened to see so many awards it deserved go to SPAMALOT.
That having been said, I actually really enjoyed it here in Chicago. DB Bonds was to me, an absolute knockout! The cast as a whole I felt was uniformly strong, and the dancers were at the top of their game, especially in Act Two's "The More We Dance." The design, choroegraphy, direction, and book/score were every bit as wonderful as I remember them from New York.
My qualms? The new opening number (The Only Game in Town) doesn't get the show off to as energetic a start as the former one did (Givin' Them What They Want)--as we all learned from FOURM, an opening number really can make or break a show. I don't think it breaks it here, but I certainly don't think it's an improvment.
Tom Hewitt overplays a little too much and while entertaining, lessens the contrast between the two leading men. Hollis Resnik is solid, but there's just no beating Joanna Gleason for dry humor. There are minor quibbles though, that don't really detract from the evening as a whole.
What I think the real problem here is? The venue. For shows that aren't larger-than-life, especially those that rely on the subtle wink-nod that much of DRS does, the Auditorium is DEATH. I vividly remember sitting in the Balcony for PRODUCERS listening to everyone in the Orchestra section laugh, and none of us upstairs. It's as if you're the kid that gets picked last for dodgeball--you feel so. far. removed from all of the action.
The space is literally twice as big (4,200) as the largest broadway house (Gershwin-1,933). (The Imperial, which housed the show on B'way, seats 1,421.)
I honestly feel this affects the audience's enjoyment of the show--how can it not when the audience feels light years away from the show? I was in row R, and it was very enjoyable, but those farther back probably had a significantly different experience.
...this bird is singing.
