You'd have to have been living in a dark cave on Kronos since at least the Johnson administration not to know that Capt. James T. Kirk (Chris Pine) is dynamic and impetuous. But just in case, early scenes confirm that he hasn't changed his ways.
    
Neither has his seemingly emotionless half-Vulcan, half-human first officer Spock (Zachary Quinto). Spock's devotion to pure logic endures, so too does his exactitude where regulations are concerned.
    
Despite their apparent oil-and-water chemistry, of course, the two share a deep bond. They also collaborate successfully in providing leadership to the intrepid crew of the Starship Enterprise. This United Nations-like ensemble includes such familiar figures as Communications Officer Uhura (Zoe Saldana), Medical Officer McCoy (Karl Urban), Chief Engineer Scott (Simon Pegg), navigator Chekov (Anton Yelchin) and helmsman Sulu (John Cho).
    
The Enterprise's current quest involves a high-stakes, sometimes morally fraught crusade against Starfleet officer-turned- intergalactic-terrorist John Harrison (Benedict Cumberbatch, oozing elegant evil). Kirk and company are helped along the way by a new crew member, fetching auxiliary Science Officer Carol Marcus (Alice Eve).
    
Marcus pushes Kirk's buttons even as she steps on Spock's toes (science being Spock's traditional bailiwick). But neither she nor Harrison, it turns out, are quite who they initially appear to be.
    
To solve at least one of these mysteries, Kirk will have to resist both his own impulse to wreak revenge on Harrison – one of whose victims was someone close to Kirk's heart – and the orders he's been issued to eliminate the fugitive without trial.
    
As Kirk struggles to be true to his own better nature, with sage encouragement from Spock, the script issues a warning against employing immoral means to overcome evil – an admonition that registers as both scripturally resonant and timely. Other, equally weighty, subjects touched on include friendship and even death.
    
In connection with the latter topic, it cuts somewhat against the grain that McCoy manages to produce a deus ex machina-style plot reversal by means of a chemically engineered resurrection. Christian viewers may be willing to dismiss this as either trivial or desperate. But it doesn't help matters that Spock, at another juncture, flatly denies the possibility of miracles.
    
Perhaps only a great theologian like St. Thomas Aquinas could work through such a contradiction. A saying attributed to him holds that everything that happens has a natural explanation; and everything that happens is a miracle.
    
Many youthful viewers may lack the angelic doctor's far-seeing wisdom, and may also be edged out of the appropriate audience for "Star Trek Into Darkness" by the elements listed below. But at least some adult guardians may consider the picture acceptable for older adolescents.
    
"Star Trek Into Darkness" will be shown on both Imax and conventional screens.
    
The film contains much bloodless battling but also occasional harsh violence, some sexual content – including a trio glimpsed waking up together and scenes with skimpy costuming – a few uses of crude language and a half-dozen crass terms. The Catholic News Service classification is A-III – adults. The Motion Picture Association of America rating is PG-13 – parents strongly cautioned. Some material may be inappropriate for children under 13.
