I saw Wicked in London and wasn't overly enamoured - it sorely needed a big number at the end, the show just fizzled out. And humour based on malapropisms is lazy. Also, I found the songs rather unmemorable, though I now like about four from repeated CD listens. And the wheelchair sister was cloying.
Apart from that, it was great
Anyway, to scenery - I was most confused by the huge dragon over the stage, and clock dial at the back. Neither came into play, though the occasional dragon flashing was cute. I understand that these bits of design make sense if you've read the book, but what's the point of including them on the stage if they're not referenced? Was it Chandler or Hammet who had that rule about that said (I paraphrase) if you introduce a gun into the first chapter, it's got to be used by the last.
Tonight the world is just an address
