Upon finding out that neither of my best friends had seen a complete episode of Star Trek, I immediately scheduled a Trek marathon to educate those unsubcultured fools - but having as many choices as there are, I'm not certain which they should see. Assuming there'll be time for no more than ten episodes, and probably closer to four or five, what would you all say about the ones that give the best introduction to the universe and the show? They may or may not be synonymous with the -best- episodes... but either way I'd appreciate your opinions. :]
