Every time I watch this movie, I seem to like it a little more. While it has nothing on the movies surrounding it (Wrath of Khan and Voyage Home) I always enjoyed the premise of the entire crew pulling together to save Spock. It continues the theme of sacrifice introduced in the Wrath of Khan and really finishes the story. I would have to say the destruction of the Enterprise was the high point of the movie, a truly bold move by the writers. While not as good as any of the even Treks, I feel that this is by far the best of the odd ones.
