Re: Which movie is most like a TOS episode?
Star Trek V: The Final Frontier has always felt the most like an episode of the series. It's very episodic, and despite the big themes, is mostly focused on Kirk, Spock, and McCoy.
Doesn't make it a great movie.
Exactly this. It's the only one of the TOS films with a teaser, at that.
