The Coal Exchange, in Cardiff, is the location for NTW's 10th Show. Tonight it was the home or Mappa Mundi's version of Dangerous Liasons. I went with John, Catherine and Kully, NTW:10's Director. It's an amazing building and the company had done a great job of lighting the cavernous space. They had managed to develop a strangely intimate experience despite the majority of the several hundred seats being unoccupied behind us. The first half was a little slow, the second half was much better. How about that for theatre criticism?
