Against orders, Kirk and his crew smuggle the Enterprise away from headquarters in order to retrieve Spock's corpse from Planet Genesis as the presumed dead doctor's consciousness seems to have taken over Bones. Meanwhile, with the Klingons closing in, Kirk's son leads a separate expedition exploring the rapidly evolving characteristics of the targeted planet. Leonard Nimoy directed this supremely uninspired installment, which has been credited by some for keeping with the spirit of the series and for its admittedly strong special effects, though the movie is awfully uneventful, cheesy, and sluggish.
** out of ****
