Tessa Thompson and Chris Hemsworth in Men in Black: International.

Men in Black: International, the fourth film in the MIB franchise, is the second-worst of the group, after Men in Black II. The original and Men in Black 3 were good; International, meanwhile, is a wasted opportunity—an admirable attempt to restart things that doesn’t hit all its marks.

Replacing Will Smith, Tommy Lee Jones and Josh Brolin are Chris Hemsworth and Tessa Thompson, as agents H and M. H is the bold, brash, super-hot dude of MIB; he saved the world years ago, with Agent High T (Liam Neeson) of the London MIB branch, from an evil alien force called the Hive.

M is the latest recruit, having found MIB’s secret headquarters after years of searching. As a child, M witnessed an alien encounter (and saw her parents getting their minds erased), starting a curiosity fire that doesn’t get put out until Agent O (Emma Thompson) gives her a chance to basically save the world as a probationary agent.

Tessa Thompson is great in anything she does, and she is great here. She brings a fun energy to the role, with a slight wiseass edge. Hemsworth is a performer who seems to like himself a little too much, yet he still manages to be likable. The two make a good pair, as they did in Thor: Ragnarok.

While it is fun to see Hemsworth and Tessa Thompson onscreen together again, the screenplay they’re following is a bit baffling. Matt Holloway and Art Marcum, two of the many writers on the original Iron Man, take a hack at sending the duo on a global adventure. The globetrotting, which includes Paris, Italy and Marrakesh, lacks a true sense of purpose—which is surprising, since the characters are trying to save the world.

After a fairly strong start, the action, presented by director F. Gary Gray (Straight Outta Compton), devolves into sloppy boredom. With each passing location, it seems as if the movie is directionless, merely picking new locales and switching up the scenery to disguise the fact that it is actually going nowhere.

A “mole in MIB” subplot doesn’t help matters much, with villain’s identity being ultra-guessable. A finale in Paris (after opening in Paris) offers few surprises and no thrills. The movie ends with a big old “Huh?”

The special effects are pretty good, with a few new aliens, most notably a little one named Pawny (the voice of Kumail Nanjiani), adding sporadic fun. I also got a kick out of a mini-alien posing as a beard on some dude’s face.

F. Gary Gray has another sequel on his resume, that being the lousy Be Cool, a sequel to Barry Sonnenfeld’s Get Shorty. Sonnenfeld, of course, directed the other three MIB films. Conclusion: F. Gary Gray needs to cease and desist directing sequels to Barry Sonnenfeld films.

This project was originally supposed to be a crossover with the Jonah Hill 21 Jump Street franchise. I’m guessing Warner Bros. soured on the notion of turning MIB into a joke, figuring they could reboot and regenerate revenue on the franchise while staying within its own established universe. Given Gray’s failed film, they figured wrong. No doubt: A Men In Black comedy with Channing Tatum and Jonah Hill would’ve been automatic box-office gold. This one is a dud.

The Godzilla film sort of sucked. The X-Men are bombing … and now this. This summer-movie season so far has been a cruel, unforgiving place for big movie franchises.

Men in Black: International is playing at theaters across the valley, in a variety of formats.
