There are two things that make ST V enjoyable:
- The dynamic between Kirk, Spock and McCoy, and
- of course, Laurence Luckinbill. He knocks it out of the park as Sybok. He's charismatic and likeable, but still ruthless. And I love that one bit where Kirk (I think it's Kirk, anyway) says "You're insane!" and Sybok pauses, clearly uncertain about it...and then says "We'll see." Like Sybok realizes in that moment Kirk might be right.
Also I like the fact that when the Ent-A crew go down to Nimbus III to stop Sybok, they bring a trained team of Starfleet Marines (yes, they are Marines - they wear dark blue turtlenecks) down with them. Didn't do much GOOD, but at least they tried!
