The sequel to the original 1995 “Bad Boys” was long in coming: “Bad Boys II” didn’t show up until 2003 (and it was so true to the titular adjective, one wished it never had).  It’s taken nearly seventeen years for a third installment, and the time was not well spent: “Bad Boys For Life” is endlessly awful, a throwback that should have been thrown away.

The premise is that long-time partners Mike Lowrey (Will Smith) and Marcus Burnett (Martin Lawrence) are still cruising the streets of Miami in their muscle car, sending their short-tempered captain (Joe Pantoliano) into paroxysms with their rule-breaking ways.  (If the setup reminds you of innumerable buddy movies of the seventies and eighties, let alone tons of TV series from the time, your memory is working fine.)

But Marcus, a first-time grandpa, wants to retire and help raise the new baby, while Mike has no desire to change his routine, intent on continuing his street-wise swaggering indefinitely.  Marcus does exit the force, but, as the saying goes, he’s forced reluctantly back into the game when Mike is targeted by a would-be assassin, and makes a recovery (one depicted as remarkably quick and easy) from what certainly seems should have been a fatal assault.

The question is who’s responsible, and why.  The answer has been telegraphed from the very start, when we’re shown Isabel (Kate del Castillo), the bloodthirsty widow of a Mexican drug lord, escaping from prison in an extraordinarily nasty scene, and encouraging her son Armando (Jacob Scipio) to take vengeance on Lowrey not just by attacking him, but making him suffer by first killing everybody involved in her late husband’s downfall. 

That leads to a string of big set-pieces, including a frantic chase involving cars, motorcycles and helicopters, and a series of bloody killings (including one of a major character) before Mike and Marcus travel to Mexico to take on the dastardly duo in a finale that turns into a literal conflagration, with Mike coming to terms with his past and Marcus kvetching all the way.  It closes, however, with a big revelation about family secrets that might just remind you of that in the last of Smith’s other recent action extravaganza, “Gemini Man” (if you were unlucky enough to see that Ang Lee bomb). 

Along the way the duo pick up a team of Miami cohorts, a special ops team called AMMO headed by Rita (Paola Núñez), who has a past with Lowrey (and she’s not the only one), and including svelte sharpshooter Kelly (Vanessa Hudgens), beefy computer wizard Dorn (Alexander Ludwig) and cocky know-it-all Rafe (Charles Melton).  They all make it south of the border for the finale, too.    

The directing duties of “Bad Boys for Life” have passed from Michael Bay (who must make do with a cameo here) to the Moroccan-born Belgian duo of Adil El Arbi and Bilall Fallah, billed as Adil and Bilall, but the basic approach remains the same.  They offer up tons of action, shot by Robrecht Heyvaert and edited by Dan Lebental and Peter McNulty in the hyperkinetic style that’s obligatory nowadays and accompanied by an overbearing score from Lorne Balfe.

But they also leave plenty of room for banter between the two stars, which is meant to be explosively funny but comes off as pretty lame, with Lawrence in particular struggling to wring laughs out of lines that wouldn’t even merit inclusion in a stand-up routine (which is what he often seems to be attempting); he also has to try to sell multiple instances of his trying to stifle throwing up at the sight of blood, which seems an odd reaction from a guy who must have seen beaucoup violence during decades on the streets.  (A conversation between the two on their plane ride to Mexico, which sends their fellow passengers into fright at the mention of guns and mayhem, is cringe-inducing.)  Presumably all the gabbing is intended to humanize the characters, but there’s entirely too much of it, especially in the first hour (which frankly tends to crawl along) since it’s mostly composed of stock back-and-forth repartee. 

Perhaps one has to give Smith and Lawrence credit for trying to pull off this old-fashioned blarney  at all, but the fact of the matter is that their reunion doesn’t engender as much affection as impatience, and when the suggestion of a sequel comes at the close, it seems more like a threat.  Enough, already.

As for Adil and Bilall, they’re reportedly also attached to direct another installment of the old “Beverly Hills Cop” franchise with Eddie Murphy.  The last movie in that series came out in 1994, which means that when the new one appears, more than a quarter-century will have elapsed.  Can you smell the mothballs?
