I think it got all the Kirk-Spock-Bones beats down very well. I think the rest of the cast were very poorly handled.I would agree that STAR TREK V got all the character beats perfectly. On that basis alone, it becomes one of the better movies of the entire bunch.
When V is on top of it's game, it did well. When it tried to do comedy or any interactions outside of the big 3 it languished more and more.
