Order is restored to the strip-mined franchise by turning its history and relationships on their heads, with young rebels Kirk (Chris Pine) and Spock (Zachary Quinto) competing even as they battle a Romulan baddie (Eric Bana) in this smart, immensely satisfying, eye-popping reboot from “Lost” creator J.J. Abrams — which features a deeply affecting appearance by Leonard Nimoy as the elderly Spock.

(2 hr 6) PG-13. (sci-fi violence, sexuality)
