The only fault I found with it, was that (at times) the lines were given to quickly.
Ex. Recall the movie, and the scene with the villagers and wanting to burn the "witch". The idiot villagers (Idle, Cleese and Palin) had to pause to think when answering Bedivere's questions.
In this show, those pauses seemed not long enough, or non-existent.
The surprise of the night, however, was when "god" appeared to give the Knights their quest.
In the movie, god was a Gilliam-animation. In the show, its just a massive set of feet that come down from above, then later they blast off (literally, like god had rocket-powered feet).
The big surprise was the voice of god.
John Cleese.
The songs were very good, and included 1 of Eric Idle's mainstays...Bright Side of Life (from Life of Brian).
