Was very enjoyable. Spoilers follow.
The movie was a lot of fun, and managed to hit a good mix of serious and light-hearted. I liked it much more than I did Into Darkness, and it might just be my favorite of the the Abrams Star Trek movies.
As my favorite Star Trek blog calls it: it was a romp. It was a lot of fun and struck most of the themes that make Star Trek what it is—interesting characters, healthy optimism, underlying themes of unity, courage and friendship, and struggles both personal and epic. Take out the destruction of the Enterprise and squeeze it down to under an hour and the movie would have made a great TOS episode.
The visuals are of course simply beautiful (something true of the Abrams movies in general). The outfits, locales and effects in general are well done. The sequences of scenes showing life aboard the Enterprise and Starbase Yorktown are smooth, informative and impressive without being overwhelming. In fact, I would say that the scenes aboard Starbase Yorktown does one of the best jobs of showing off life in the Federation in any iteration of Star Trek.
Finally, the movie also does a good job of addressing Nimoy’s death (and the loss of the one of the main characters of both this, and previous iterations of the franchise). It’s not overly dramatic, but it is respectful, elegant and helps drive the rest of the story forward. And I absolutely love that one of the final shots of the movie is this photo of the original cast:
The movie wasn’t perfect: the action seemed choppy, some of the humor was unnecessarily forced, and some of the science was suspect. But it was a damn good Star Trek movie and a good movie in general. Would watch again.
