Picking up where "The Wrath of Khan" left off, McCoy seems to be going mad, the Enterprise is being retired, Kirk mourns the loss of Spock and his son Dr. David Marcus is off exploring his newly created Genesis planet with the lovely Vulcan vixen Saavik (exit Kirstie Alley, enter Robin Curtis). Kirk then finds out from Sarek (Mark Lenard, who had a brief, unrecognizable role in the opening of "Star Trek: The Motion Picture" as an ill fated Klingon Commander and played a Romulan before playing Spock's dad) catches up with Kirk and tells him that there's a chance at resurrecting Spock, who's mind and spirit are housed in McCoy's brain while his body is on Genesis. Feeling obligated to return the favor for saving them all at the end of #2, Kirk and the gang hijack the Enterprise and rush towards the Genesis planet to rescue Spock "in whatever form he may still be alive." Meanwhile, a bodily resurrected and rapidly re-aging Spock has been found by Saavik and David and they are stranded on Genesis after their ship is destroyed by Klingon Commander Kruge (Christopher Lloyd) and he comes looking for them in hopes of unlocking the secrets of the Genesis project, which he thinks could be used as a weapon against his people. Who will survive?
Considered by some to be trash and by others to be the only good odd numbered Star Trek film, this is a sufficiently entertaining bit of science fiction yarn that continues following the theme of what happens when you mess with mother nature. Good performances as usual, with Lloyd giving one of his best as the Klingon Commander Kruge, who becomes oddly sympathetic in light of his blood thirsty actions when you consider that he was just looking out for his own brood and was willing to spare the crew of the USS Grissom. Shatner's brawl with Lloyd is also fun to watch, and the film still has that great James Horner music. Don't miss Shatner kicking Lloyd in the face shouting "I... have HAD... enough of... YOU!"
Robin Curtis is a capable Saavik. As a bit of trivia, Saavik apparently engaged in sexual intercourse with Spock while he was going through his aging phases and, as part of an idea never utilized in the films or even in the spin off series, Saavik became pregnant with Spock's child, which was originally why she was supposed to stay on Vulcan in "Star Trek 4: The Voyage Home".
