The amount of enjoyment you get from this film will depend on how well you click with the script's humour. Like Andrew Bloom points out in his review, the film is carried by the dynamic and pathos between Kirk, Spock, and McCoy, although I would extend that to the Enterprise crew in general. I found the humour the saving grace of the film, which is a better overall watch than I remembered.

It's certainly one of the weakest Trek movies, alongside _The Motion Picture_, but it's still very enjoyable thanks to the cast's efforts and the dialogue rather than because of a coherent or satisfying plot. A promising first act is undone by the fairly shambolic second.

Still, it's an enjoyable if fairly frivolous watch. For non-Trekkies, this probably would be in the 5 / 6 territory but if you're a fan of Kirk, Spock, and McCoy, then it's certainly not as bad as many fans like to say.
