This used to turn up at 3AM on those stations you had to stick a coat hanger in the back of your TV to get semi-clearly, but I haven't seen it crop up in twenty years now. Aliens conquer the Earth, but the twist is that they bring peace and prosperity and the population rebels against it.

Worth a look if you ever stumble across it.
