The film had just great action scenes. The first film peaked with the fight on top of the mining device, where James Kirk and Hikaru Sulu fought off the Romulans trying to destroy Vulcan, but Into Darkness upped the ante.
The first really great action scene came when the away team landed on Qo’noS and got into a firefight with the Klingons. Saved, only by Khan himself, who made short work of the Klingons.
Then there was the space dock scene, where Kirk and Khan get blown out of the airlock and have to travel to Admiral Marcus’ ship covertly. Not to mention, the scene where Kirk, Scotty, and eventually Pavel run through the ship as it’s falling out of orbit.
And we’d be remised if we didn’t mention the final chase between Khan and the only member of the crew who could match him move for move, thought for thought, Spock. The chase was among the more unique things we’ve seen in a Star Trek film, as I can’t really recall the last time a foot-race concluded the rising climax of a film, but that’s exactly what happened here. And not only that, but we got a pretty neat look at how Earth has evolved over the years during the scene.
