Well, it was better than the previous "new" Star Trek films. Slightly. It started off great. I loved the opening scene showing a diplomatic Kirk in front of an assembly of humanoid-mini-lions(??). The Starbase Yorktown looked amazing. A Starbase that was basically an entire world, with cities and skyscrapers? So cool. So far it was seeming more like a Star Trek film and less like every other action movie made in the past ten years. Then it proceeded to turn into every other action movie made in the past ten years. Explosions, fight scenes, jumpy cameras.
The plot was OK, though it mostly consisted of them wondering around "Endor" trying to survive. I do enjoy when the Enterprise crashes, it always looks awesome. Plus these villains are just insane. That ability to swarm and burrow... damn that was awesome. However I did not find the main villain Krall to be that interesting. Still, the way Kirk and crew finally defeat the swarm is pretty great, and funny. The character Jaylah was very good... sort of a Rey rip-off in a way though.
The cast in these films are great. Quinto is just so damn perfect as Spock. Pegg is fun, Pine, Urban and the rest never seem to fail. The movie had nice little tributes to Yelchin and Nimoy. George Tekai was disappointed that they made Sulu gay, a character in which he says had been straight this entire time only to suddenly not be. Which I get. But, remember, this is supposed to be an alternate reality. So this gives them the ability to basically do anything without messing up the shows continuity. Which is VERY convenient.
