Star Trek: TOS 1.04: "The Enemy Within"
It only took five episodes to get to the very first transporter accident. The wrath of those infernal machines will extend for at least the next 113 years. I might blame Richard Matheson for that, but I'd rather thank him for the first solid episode of the show. I'm not surprised such a talented writer was the man to establish the essential Kirk-Spock-McCoy triangle.
Evil Kirk: a tour de force performance from one Mr. William Shatner. Thank you, Bill.
