my first reaction to this documentary is sadness for the families that then and now suffer from the lost of their loved ones from cancer. I couldn't imagine being one of the doctors responsible for finding the cure to help those children by making them suffer more so from the treatment  and being unsuccessful for the ending result to be that the children died. i would imagine that the doctors responsible for their efforts in finding the cure for those children couldn't have been easy at all and I commend them for taking that choice to trying to save the lives of cancer patients with such passion.
