Revealing mistake: At the party, Jamie finds the crashed plane. His glider falls behind a small hill and he gets out of the plane to see where the glider is. When he jumps off the wing, the camera is panning to the side, revealing somebody on the left side walking on the hill, right under the tail of the plane. Jamie should see this person but still reacts shocked to see people are behind the hill. (00:17:00)
Revealing mistake: When Jim is riding the bicycle through the empty hospital, the "Frigidaires" begin falling through the roof. One bursts open, dropping its contents onto the floor. Something from inside must have landed on the camera because you can see it jerk suddenly.
Answer: I don't think anyone disliked Jim or was mean to him. Basically, he's a somewhat annoying, overly-active kid that the adults, who are in a very dire situation, simply didn't have much patience or the inclination to deal with. Also, the adults are mostly upper-class British, and in that era and before, they tended to be stricter with and more dismissive of children.
