Formally it resembles so many films of the era, and like many it contains loads of latent social fears and subversions. Its ending alone is one of the best depictions of the limits of the rational ego. The rest is kind of cute, struggling to live up to the shocking beginning until its end.
2-2.5. Maybe deserves extra credit for its conceptual side, but the first act is a bit too short, the film invests too much in the development of the children, and they're mostly never allowed to exercise the potential that would have made them fully scary. They actually don't kill anyone onscreen who didn't seek to do them harm first. Kudos to the actor playing David, though; they were right to give him the lines.
Superb low budget early 60s horror/scifi. This is the kind of movie hacks like M Night Shymalan wish they could make. I love me some George Sanders. He could read the phonebook and I would be enthralled. This one feels a bit like an extended Twilight Zone or Outer Limits episode, very creepy but doesnt get too bogged down in the details and leaves a lot up to the audience. 4.5 stars
A wooden and clunky British B-Movie with an interesting idea behind it, like a lot of speculative sci-fi. Could just as easily be an episode of Doctor Who or a bit from the Twilight Zone. Can't figure out if there is some kind of Nazi metaphor buried in here or not...
