The film was a prime example of how bad directing can ruin a film. That material with that cast should have been dynamite, but the director didn't understand the story one bit, and so it really is quite dreadful.
Thankfully, in 2014, LA Theater Works recorded a radio-play version with much of the original cast, including Deanna Dunnagan, Rondi Reed, and the late Maryanne Mayberry. You can purchase it for $5 from Amazon or Audible. For me, while the recording doesn't get close as the amazing experience of seeing that play live, it captures a great deal of the greatness of that play and those original performances and helped wash away the taste of the misguided film. I promise I'm not a shill for LATW, but I think they're a really great company with an incredible catalogue that so many people don't know about.
