The outer limits was brought back by Showtime a few years ago, and is now being done by The Sci-Fi Network. I remember one a few years ago where aliens land and address the United Nations saying that we were one of their experiments, and that we had failed to produce results so we were going to be destroyed. The UN delegates begged and pleaded for just 24 hours to set things right and save the planet, and over that 24 hours they worked out a plan for world peace which was signed by all countries. The only problem was that when the aliens came back, they informed the UN folks that the reason they were going to destroy us was not because we were too violent, but because we were not violent enough. They had planned for us to act as an army. And since they worked out a plan for world peace, they proved they were unworthy to live and the planet was destroyed.
A bit twisted, but I thought it was an excellent show.
