I think it's worth a watch, yes. Patty has the luck of having most of the memorable lines/moments, but I do think there's something compelling about her performance as Neely. You can buy her as not only an unmistakable talent but a complete lost cause. Mileage may vary on Barbara Parkins' performance -- I should revisit it, as my memory is that she's just too serene for the scene. And Sharon Tate's really quite gorgeous.
