Zachary Quinto, Benedict Cumberbatch and Chris Pine in Star Trek Into Darkness.

When director J.J. Abrams created the alternate timeline with his brilliant 2009 Star Trek reboot, it gave the franchise a chance to construct all new adventures for Kirk and Spock. It also gave Abrams the opportunity to mess around with variations on characters and adventures that we have already seen.

Such is the case with the exhilarating Star Trek Into Darkness, a movie that includes elements of Star Trek II: The Wrath of Khan and “Space Seed” (a classic Trek TV episode).

The film starts with Chris Pine’s cocky Kirk getting himself into more trouble. He ignores Starfleet directives and rescues Spock (Zachary Quinto) from an erupting volcano, allowing a primitive alien species to set their eyes on a big UFO in the form of the U.S.S. Enterprise. Kirk gets demoted by Admiral Pike (Bruce Greenwood), but keeps a relatively high rank thanks to his pal Pike pulling some strings.

Back on Earth, a bomb goes off in London courtesy of renegade Starfleet officer John Harrison (Benedict Cumberbatch); that same officer attacks a gathering of Starfleet commanders soon thereafter. He is pissed off, and anybody in a Starfleet uniform is his target.

Kirk and Spock find themselves en route to Klingon territory, where their homegrown terrorist has gone to hide. They have unorthodox directives from Admiral Marcus (Peter Weller) to target and assassinate the terrorist from the skies using torpedoes. (Echoes of drone targeting and the U.S. hunt for Osama bin Laden, right?)

So … you have Klingons, terror in London, commanders getting attacked and volcanoes erupting with Vulcans in their belly. That’s a pretty damned good start to a sequel, no?

The true identity of Cumberbatch’s character might not come as a surprise. Heck, his real character name is listed in the cast on IMDB.com. As for me, I remained in the dark until some jackass uncorked a spoiler on the Internet a few weeks ago. Damn you, Internet reviewer. Damn you! The Internet is a fun thing, but it sure does wreak havoc on those fun movie secrets.

Abrams gets a little heavy-handed with the Sept. 11/War on Terror allegory, but he still keeps his movie effective, and even moving at times. As for his use of a tribble—the furry pests the Enterprise contended with in a famous series episode—it is my least-favorite part of the movie. The way the tribble is utilized makes no sense and feels like a stretch.

Abrams also oversteps a bit with pivotal late scene between Kirk and Spock that is a mirror version of an infamous scene in Khan. I don’t mind him messing with the Trek legacy, but keep it original. Bring back some famed characters, and hint at moments from franchise past, but don’t blatantly copy them. There’s a moment when Spock yells a particular word that got unintentional laughs from me.

Cumberbatch does a great riff on an old adversary, and his deep voice is one for the ages. He’s one of those anything-can-happen movie villains who is frightening, yet oddly virtuous. Weller gets his best role in years as Marcus, a flawed man with an imperialistic agenda that might have some people viewing him as the film’s real villain.

Alice Eve is another memorable new addition as Carol Marcus, the admiral’s daughter and a stowaway on the Enterprise. Some of you might remember a scientist from a previous Star Trek film with that same name. Well, from now on, you’ll remember Eve, who has an obligatory underwear scene that is right up there with Sigourney Weaver’s out-of-nowhere strip in the original Alien.

Pine and Quinto might not have you forgetting Shatner and Nimoy, but they have established themselves in their roles and can probably own them as long as they want. Zoe Saldana has many shining moments as Uhura.

Simon Pegg’s Scotty, John Cho’s Sulu, Anton Yelchin’s Chekov and, especially, Karl Urban’s Bones all contribute to the party. The Star Trek franchise gets the award for Best Reboot Casting.

If you see Star Trek Into Darkness in 3-D, know that this is retrofitted 3-D. It looks OK, but you are probably safe to take in the 2-D version (although the Abrams lens flares do look pretty cool in 3-D; the man loves his lens flare).

For a film called Into Darkness, there are many, awesome shots of the Enterprise during the day. It’s interesting to see a ship usually cloaked in darkness sailing around in daytime skies, and even going underwater at one point.

There’s a pivotal chase scene in which Kirk and Spock pilot a ship that has a Millennium Falcon vibe to it. That had me thinking about the next Star Wars, and what Abrams—who will direct—plans to do with it. Abrams has a grasp on major geek real estate with these two franchises. He’s, like, the Godfather of Geeks, and he could destroy all of us with a bad chapter in either series. He’s a powerful man capable of great good—or insurmountable evil.

Fortunately, he used his powers for good with Star Trek Into Darkness, a solid piece of summer entertainment.

Star Trek Into Darkness is playing in theaters across the valley.
