I'm glad that I subscribed to this thread, so I could find out now about the demise of the show, rather than waiting to find out info, hit or miss.
corprip: Although sad news, I appreciate you finding it and posting it. The final show reminds me of the one that ended ANGEL: much promise, much plot threads...never to be tied together again.
Maybe, just maybe, PAX TV would/could pick up JOAN.
