Kind of a poor mans (or directors) blend of 'Invasion of the Body Snatchers ' and 'The Day The Earth Stood Still.' Martians invade, but they are incorporeal, so the treat of this film is that the chills are mental, there are no bad costumed Martians here. The pace was OK, but younger audiences wont be able to tolerate it. I found watching this to be easy, the dynamic of the scientists family was interesting to observe , due to their normality. The film overall creates a spooky atmosphere as it builds, almost like a Rod Serling effort. The set is a wondrous manor that is actually located in Beverly Hills and was later turned into a park that you now pay to see and walk through. The conclusion of the film is unorthodox, a rare 'unhappy' ending for sure. Five stars.
