Say what you will about The Search for Spock as a whole; that sequence in which Kirk steals the Enterprise and escapes spacedock is one of the most engaging I can think of in all of cinema. Everything from "Don't call me Tiny" to "The doors Mr. Scott!" "Right sir! I'm working on it!", "Oh, I'll have Mr. Adventure eating out of my hand." all the way up to "Kirk, you do this, you'll never sit in the captain's chair again." It's an incredibly emotionally charged scene that is simultaneously tense, funny, and thrilling even though it takes place at 1/4 impulse power, there's no lens flare, and nobody gets choked or murdered or even shot at. That's classy fucking filmmaking. And scoring too! James Horner's finest work in my opinion.
