A TOS double bill of Space Seed and Journey to Babel - While I know the stories (from Memory Alpha), I haven't seen either since I was a child (some thirty-odd years ago). I think both stand up pretty well today, and are far better than most of the TOS episodes I've seen lately. Of the two, Journey to Babel is my favourite purely for the outstanding performances by Mark Lenard and Jane Wyatt. I particularly like the last scene with the two of them - the finger touch and Sarek's little smile for his wife.
