I can't say that I like many of Anderson's short stories, and all of the shows below were based on those. Not that they were bad mind you, but simply because his novels are so much better. Aliens land in England around the dark ages, and expect to take over in no time by simply shooting lasers and scaring the populace into submission. The aliens are soon beaten to a pulp and their ship taken over. The Knights then go on with the ship to try and destroy France.
Fear breeds unnatural courage.
Better a life like a falling star, bright across the dark, than a deathlessness which can see naught above or beyond itself. All demons know Latin, at least. A prayer is more in the heart than the mouth. If a dog is driven out, he will become a wolf and feed on his master's flocks. Hate is a hard master.
