In our analysis of Star Trek II: The Wrath of Khan, we join Admiral James T. Kirk and his Starfleet friends as they are once again pulled into a risky adventure. Since his infamous attempted coup on the Enterprise 15 years ago, Khan Noonien Singh is noticeably more emotional, ragged from years of hard survivorship on an inhospitable planet, but he's also deeply preoccupied with revenge. But as both the film and science can attest, achieving revenge is rarely as satisfying or as personally rewarding as we hope it will be.
