There are so many possible scenarios here and everybody fastens in on the War of Worlds thing.
How about a highly advanced people who have been whupping up on other almost as advanced peoples because their energy weapons are better.
But are feeble and helpless when physically attacked with swords? Or when naked fighters race in (no metals or chemicals to give a high tech signature) and just beat them to death with kung fu or wedgies or something?
I remember one movie where the aliens were killed by ****-kicking music.
I believe that movie was, "Mars Attacks", IIRC.....good movie; had a corn-ball plot to it, but a good movie, though........
