Profoundly fascist movie.
The sheep choose to bring back their overlord and go back to eternal servitude for no reason (other than sustaining the status quo I guess) instead of running the farm themselves (they are clearly shown to be able to use public transport and kidnap a man, you can’t tell me they can’t sustain themselves).
It is unclear why the sheep may need their master’s protection other than the bizarrely violent and completely imaginary character of the animal…
