I have also heard good things about this movie and ordered it from Amazon. I am waiting for the weekend to watch it. I live with scientific type brains who like to have concrete explainations for the things around them, which I don't get as I can think of many things that they accept on a daily basis without explaination.
As to the 'faith healer' portion of this thread consider how it is done. The 'laying on of hands' etc. I think that they are mimicking(sp?)what has been written without any understanding of what they are really doing, the energy involved, and even the science involved. Also to be considered is why 'sometimes' it works(the faith healers)and other times it does not. Most of the time 'not'.
