This movie looked somewhat interesting in the vein of classic British Sci Fi (even though it is an American film) and this illusion remained for about the first 15 minutes of the film!
After that it quickly turned into a paranoid cold war drama with fairly uninteresting sequences and shaky sets. I won’t spoil the whole story for you by giving out too many details, but this is not exactly the best film ever made.
Having said that, it was not entirely unentertaining and maybe worth a peek on a wet Saturday afternoon.
