This link leads you to a variety of sites where claims made in What The Bleep Do We Know? are critically examined, and boy, do they need to be critically examined! We watched this movie in a seminar at Saint Mary's and by the time it was over my eyes were tired from rolling back in their sockets for nearly two hours.
Later in the same class we watched the 1990 film, Mindwalk, which was much more compelling. Not much happens, but the dialogue grows on you. Don't know where you'll find a copy; Netflix seems not to have heard of it.
