Not knowing anything about the play, I was overwhelmed by this nearly six-hour presentation. It is certainly not a perfect piece of filmmaking (sometimes too much over the top), but scores a perfect mark in shocking and unrelenting confrontation and dialogue --as well as some of the most wild and imaginative mix of drama and fantasy. Dark, depressing? You bet. With sharp and clever dialogue...probably one of the top HBO production ever created. Kudos to all.
