It's pointless to show TWOK without first showing "Space Seed". Otherwise, how do people really understand why Khan is so vengeance-minded toward Kirk, and why he's so dangerous in general, and who is this "her" Khan mentions? Long-time fans know he means Marla McGivers, but someone totally unfamiliar with the series wouldn't have a clue. Gah. Does this person not understand the concept of franchises and spinoffs? TOS is the original series and everything else is a spinoff. It shouldn't be too hard to understand that concept and that the spinoffs have different casts but most of it is set in the same basic universe. At this point I'd avoid nuTrek, since it's hard enough to just get into the series without explaining alt-universe series. The first episode I ever saw all the way through was "By Any Other Name." I'm not recommending that as a good starting place, but it was enough to grab my interest and make me want to see more. Two weeks later I had to admit I was hooked and have never gotten un-hooked. That was 42 years ago.
