A group of trouble making teenagers from earth cause more problems than the giants.
In production order, this is one of the first seven episodes of Land Of The Giants, in these early episodes the giants were mostly silent and it was in fact the earth "little people" that stole the hours totally...because they got more to do and say. The Lost Ones is no exception.
The trouble making lads from earth are perfectly cast in the roles, and this is the only time in the whole 51 episodes of the series that the regular cast have a whole group of other "little people" to act with. In season two's Wild Journey the little people would get TWO other people to play around with, but never again would they get a whole group.
The conflicts with the boys are at times a bit intense - "Captain Burton I am going to break every bone in your body" - which also makes it the darkest hour in Land Of The Giants.
In the 1970s, Australia was one of the very few places in the world that was willing to replay Land Of The Giants, but The Lost Ones was kept out of the re-run package as it was decided it was too grim for afternoon kid-hour re-runs. And frankly, as much as I love the hour, I think it deserved such treatment
