Just too short or abridged in the audiobook - but it got all of the major points of the movie in, so that's something. Loved George Takei's narration, with the little bit of Leonard Nimoy's for good measure.

5/14/21 - listened to the unabridged version - don't remember exactly how it compares to the real audiobook, but this was nice and full, some new scenes, everything from the movie, and also said to myself a couple times, "oh, so that's why that was in the movie". So the full book is definitely better.
