This movie lost all credibility...
...when that old broad with heavy make-up who calls herself Ramtha appeared. All seriousness was lost when she started babbling all her utter nonsense. I bought this film because Marlee Matlin appeared in it, thinking it was a regular movie. All the pseudoscience the people in the film explained was sort of interesting (even if it's simply impossible to swallow for me), until she appeared. It destroyed all sort of credibility the film had tried to establish.
The Columbus ships part was laughable too...
