I don't think this one suffers from the curse of odd-numbered Trek movies. It's not as action-packed as "Wrath of Khan", but it's not meant to be. There's something really cool in the idea that Kirk and friends are willing to sacrifice their careers, maybe even their lives, for the life of a friend who could still be dead. The theft of the Enterprise is more exciting than the starship battles in "Khan", and its destruction was sad (a final look at the bridge from Kirk just before he left would've been nice, though). Spock's reunion with his fellow crewmates is well done. Christopher Lloyd makes an okay Trek villain, although he's no Kang. And it's nice seeing Mark Lenard reprise his role as Sarek.
