I have seen DRS twice now and absolutly love it. I saw Spamalot on a Saturday and DRS the next Tuesday and couldn't wait to go back to DRS, I won the lottery last night! I have no desire to see Spamalot again.
I think that DRS works so much better than Spamalot, especially in that it does some of the same tweaking of musical theatre styles without being stupid about it (Laker Girls? "I am alone"?)
The performances in Spamalot didn't do anything for me in comparison either, Joanna Gleason was at least equal to Sara Ramierez, as Jbara to Borle or Siebler, I thought Curry was completly misused, and Azaria/Hyde Pierce were good but not as good as Sherie Rene Scott.
Norbert was a thousand times better alone than anything in Spamalot.
All of this from an avid Python fan who loves Holy Grail.
I'll still buy the Cast Recording, but a return visit to the show is close to "only if you pay me."
I stand corrected, you are as vapid as they say.
