Making the first relevant social commentary in Trek in over 20-25 years while telling an entertaining story.
Social commentary is nice, I just have a hard time taking it seriously with what we've got. The film tries to convey that "weaponizing" starfleet is bad even though the Enterprise, not the USS Vengeance has more torpedo bays than all the previous Enterprises combined, including the Enterprise E which was built more towards combat. Or the fact that Kirk tries to send a message that revenge is wrong, despite everything that has gotten our characters to this point was thanks to revenge. Khan acts out his vengeance and winds up getting more than what he wanted. The bad people dead and his followers safe.
