Review
I believe Star Trek III is an underappreciated film in part because it is not accessible to a general audience. It is a pure science fiction film. In my opinion it is the one odd numbered film in the series that isnt victimized by the curse of uneven numeration. I enjoyed the film because of the exciting action and fight sequences the nostalgia and the developed characterization of characters I am already so familiar with. I also found the film to be surprisingly spiritual and revelatory a rarity for a sequel in a commercial film franchise. Anyone with close friends will be touched by Kirks loyalty and sacrifice for Spock. Highly recommended 810.
