It was... enjoyable on the whole, I suppose. But there were just too many moments that utterly killed the tension and/or pacing for me. One in particular really just ruined the rest of the movie for me; The scene where Kirk "dies" has NO WEIGHT WHATSOEVER, because of poorly delivered, heavy-handed foreshadowing about magical anti-death-blood. The premise is... silly, but forgivable, BUT I literally spent the entire scene between Kirk and Spock at the radiation shield screaming in my head, "SHUT UP, HE'S GOING TO BE FINE".

There are a million little details that bug me, but those can be overlooked in service of the story. Sort of. But a major point of dramatic tension being ruined by sloppy writing is a serious no-no. (I mean, we knew Kirk wasn't staying dead, but there was NO MYSTERY AT ALL COME ON.)
