I must be crazy. Just after watching this movie, I got on IMDb to see what its rating was, and, honestly, I was expecting something a lot higher. I don't consider this movie a turning point in the film industry, but I certainly wouldn't call it bad. It's not bad. I didn't notice any flaws in the acting (which is the principle instrument for telling a movie's story)---I personally thought that Patty Duke's performance was amazing. The storyline intrigued me, and I liked the characters---especially Barbara Parkins' Anne, who I felt myself relating to by the end of the movie.
Like I said, I must be crazy. I wouldn't say this is the best movie ever made, but I thought it was rather good. I'd sit through this any day before I'd watch LORD OF THE RINGS. I guess I must have missed the horrid atrocities of this film. I'd recommend it to anyone with an interest in the darker side of show biz'.
