I've always been intrigued by mental disorders and stories about them - obsessive compulsive disorder, multiple personality disorder, schizophrenia, paranoia . . . So it's no surprise that I enjoyed this movie. It was simply fascinating. I found myself caught up in the story without even meaning to be. Joanne Woodward did a superb job in this role. That would have been a TOUGH one to pull off. Yet she managed to even LOOK different with each one of the personalities. Tons of kudos to her for this... and to everyone who decided this movie was a good idea.
