Star Trek II: The Wrath Of Khan at 40

Star Trek: The Motion Picture is much admired in retrospect, but The Wrath Of Khan was loved from the outset.

The Next Generation owed more to TMP (from the reuse of the theme music to the two-tone outfits) but Khan was what made Star Trek viable in the 80s.

And for me, the FASA RPG adventures set in this era were important as well - even if the adventure supplements generally ran at more of a TOS speed and planet-of-the-week mode, and we moved on to the then-current TNG era quickly even though FASA lost the licence soon after. But part of me still wants big movie Trek, literary references, and a nice jacket.
