Riedel has made it fairly clear that he thinks this show will fail, but his bizarre comments about the "wacky new idea" of the space shuttle ending and closing is patently untrue, as others have pointed out. I saw the show in previews in SF and the space shuttle bookends were very much in evidence.
I don't really understand his vitriol towards the show. He doesn't have to like it, and I think there are few people who would claim the show is perfect. But his "let's rah rah it to its doom" attitude is sort of disturbing.
'"Contrairiwise," continued Tweedledee, "if it was so, it might be; and if it were so, it would be; but as it isn't, it ain't. That's logic."'
