So many of you made thoughtful points about how this show works - or doesn't. I love the score, personally, and when it's sung well, with convincing singing-actors, it's a treat; literate and witty. It's what happens between numbers that can make or break it. It is very long, and you can trim a bit without killing it. Frankly, without a strong Mordred, I think the show's a bit of a wash. I didn't see the PaperMill version, but it sounds like their Mordred had the right idea. I know Roddy Mcdowell's Mordred (about 50 years ago on Broadway) was the smarmy, asexual one that was the norm for awhile. Also, it was a different world, culturally. Still, the story is mythic and timeless, and as someone said, the contest between the rule of law, and a more personal mercy and morality. There are a lot of creative folks around. There should be a way to make a Golden-Ager like this palateable to a new audience.
