Taking the reins of the Star Trek saga, producer/director J.J. Abrams’ most impressive gambit is a self-consciously clever ploy. Faced with the task of acclimating new audiences to this venerably corny space opera, he simultaneously executes a franchise reboot and nostalgia play. Thanks to the miracle of time travel — in the context of the Star Trek cosmos, such gimmick doesn’t even qualify as a stretch — Star Trek functions simultaneously as sequel and prequel. That is to say, while it brings with it the return of a notably wizened Leonard Nimoy as an elderly Mr. Spock, the eyebrow-humping logician who was arguably the signature character of the original TV series, it’s also full of origin stories. If you ever longed to see the Trek-ian likes of Kirk, Spock, Sulu, “Bones” McCoy, and Uhuru as fine young things studying together at Starfleet Academy, this is your chance.
