The very first thing that turns me off from documentaries are biased perspectives. The second turn-off is overly emotional displays meant to endear the viewer to the character. Unfortunately, this documentary uses generous amounts of both.
The fact the director is the daughter of couple probably wasn't a good idea to begin with. I felt that she was enthralled with her mother's sensitivity and she was fixated on filming her tantrums and tears. I personally found all the moodiness repugnant and hated her by the end. I was more interested in the father and his scientific accomplishments, but was disappointed by the director's passing reference to him. Instead I was fed more mommy tears and wailing.
The was the Sundance audience award winner for documentary, and I thought it wasn't a good reflection on their taste. Awful, awful, awful!!!
