Yes, there's a promising setup (the Enterprise crew is held hostage by a vicious bad guy who rules a backwater planet a la Kurtz in "Heart of Darkness"). And there are suggestions of classic "Star Trek" style action-plus-characterization-plus-cleverness, and pleasing performances by a cast that has settled into each others' rhythms, as a real-world naval crew would after years of sailing together.

But the movie never delivers on its considerable promise because it's always in such a hurry to get to the next action scene. And aside from three magnificent setpieces—the first, crippling sneak attack by a fleet of tiny ships that swarm the Enterprise like explosive bees, and two vertigo-inducing chase-and-fight scenes in which geography goes all M.C. Escher on us—the action is not good enough to be the film's main course. Lin, who proved in the "Fast and Furious" series that he could do great or near-great action, here substitutes wobbly camerawork, chop-chop editing and rumbling sound effects for suspense and a sense of spatial design. It's a step up from the action in J.J. Abrams' "Star Trek" movies, but that's not the sort of thing one should brag about. A climactic reprise of a certain overused Beastie Boys song might be the franchise's low point, rivaled only by the laughable credits sequence of "Star Trek V," which cut from a helicopter shot of a lean young stuntman scaling a craggy peak in the Pyrenees to a close-up of the 57-year-old star/director Shatner's meaty hand in a studio, gripping a fiberglas "rock."

Simon Pegg and Doug Jung's screenplay provides the right amount of homage (as when Kirk grumbles after an opening action scene that he ripped his shirt again), plus Spock/McCoy odd-couple banter and some marvelous, character-based laugh lines (Scotty demands that Kirk give an opinion on one of his engineering improvisations, because "if I mess it up, I don't want it to be just my fault"). There's psychological nuance, irony, even a political subtext (Elba's character, Krall, a reptilian Che Guevara-type who wants the galaxy's "frontier" to "push back" against the Federation's expansionism). Too bad none of these aspects are filled out with the detail they deserve. Krail's fire-and-brimstone sermonizing is turned to nonsense by a pointless and self-defeating third act "twist"—like we need another one of those after the boneheaded fan service of "Darkness"!—and there are points late in the film where "Star Trek Beyond" seems jolted by the sudden remembrance of things that it told us it was going to deal with but didn't.

Uhura spends most of the movie in a prison camp. Kirk, Spock and even McCoy have human moments, but they spend too much of their screen time sprinting through hallways, firing phaser pistols, and piloting spaceships while yelling and grimacing in tight closeup, like the heroes of every other science fiction-flavored action movie projected in theaters recently. Krall and other characters allude to the Federation's fake-benevolent brand of imperialism, but unless you're familiar with examples from elsewhere in the "Star Trek" universe or got briefed by a super-fan before buying a ticket, you'll leave with no sense of whether the villains' grievances are legitimate, much less if you're supposed to feel mixed emotions at Kirk's inevitable triumph.
