This is a classic 1970's cult film, and therefore must be viewed in that context. Attempting to review the film from a current day perspective is unfair. Viewed from the proper perspective, this film is a wonderful and delightful, and fun adventure into the unknown of UFO's, ghosts, clones, telepathy, Atlantis, ancient astronauts, witchcraft, the Bermuda Triangle and more. This film is an journey into the mysticism that was so prevalent during the 1960's and 1970's. For those who long for a good ride in the "way back" machine, this is your film. People were much less cynical and had a greater zest for mystery and adventure. This film provides that vehicle.
