It’d hard for me to rank the films, but The Search for Spock is really up there for me. It gets bashed way harder than it deserves, as it’s a perfect sequel and really packs a wallop when seen right after Khan. From a technical aspect, it introduced so much to the Star Trek universe. Earth Spacedock, the Excelsior class, Oberth class, the idea of Transwarp, the Klingon Bird-of-Prey, and the special effects to go along with it were all top-notch. The Enterprise destruction is still the second most powerful scene in all of Star Trek to me, first being Spock’s death and funeral, third being the sign-off sequence at the end of The Undiscovered Country. It’s a shame it gets overlooked by a lot of people who buy into the whole ‘odd-numbered Trek films are bad’ thing.
