Action and more actions. The whole movie there are things blowing up and much more gadgets that are used in the movie. All the cool tech and also interplanetary traveling makes you in great awe as you see cities built in space with teleporters and also people travelling with such advanced vehicles. The battle on the outer space was intense and also fun to watch. The chemistry between Commander Spock and Doctor Bones creates a bromance and it brings much live to the screen. Aside from that, Captain James Kirk seems to be much more in control comparing to the first movie and that brings out a certain sense of responsibility and security when you are watching him sitting in the captain's chair.
Well for most of the hardcore Star Trek fans, I am pretty sure this show does not appeal to them as it is much dense and lack of space explorations. Other than that, I am pretty sure the lack of strategy also hurt the understanding of audiences and characters did not have much building, therefore, you need to know the first movie really well.
If you are up for some mindless space action and also adventure, Star Trek is something you will enjoy very much. If you are a hardcore Star Trek fan, I am sorry that this movie will kill all your hopes and dreams of space exploration.
