“I Did It My Way” is a Hong Kong cops-vs-Dark Web/Drug Trade thriller that unfolds like a tragic opera, one set to the strains of Frank Sinatra’s third biggest hit.

The action, emotions and sentimental turns in the plot are heightened, but never come close to being as over-the-top as they needed to be to come off. It’s a melodrama with cops threatening gangsters — mid SHOOT OUT, mind you — with “You’ve got 15 minutes to surrender!”

Fifteen minutes? That’s awfully generous.

A mobster screams about all he’s lost and cries in fury about why the cops and their families should be spared the same heartache.

Nobody bothers to tell him, “Because you’re a drug supplier and ruthless thug who’s tortured and executed cops, rivals and anyone in your gang who could tie you to crimes, and scores of drug users have died thanks to you.”

Cinematographer turned director Jason Kwan, who helmed the “Chasing the Dragon” thrillers, does little to lift his stock with this slick-looking/dumb sounding B-movie. But the suspense plays, I’ll give him that.

Veteran producer and star Andy Lau (“Internal Affairs,””House of Flying Daggers”) plays the heavy, a Hong Kong lawyer named George Lam who always gets the bad guys out of jail and always keeps the “Boss” beyond the reach of the cops.

Eddie Peng (“The Rescue”) plays the intrepid People’s Republican cop on the case, heading a cyber crimes task force who’s trying to protect China from the perils of Silk Road and the unchecked flood of Colombian drugs about to be unleashed by The Dark Web.

And Ka-Tung Lam of “Ip Man” and “Limbo” is the mob’s top lieutenant, trusted by Lawyer Lam, and a “mole” the cops have inside this vast criminal enterprise.

Suspense here is provided by “Will they find out who our family man/undercover cop is?”

The film’s poorly-handled “ticking clock” comes down to scenes of the gang’s hackers and Dark Web business facilitators staying one step ahead of the over-matched cyber-police trying to prevent a flood of cocaine and “Super Molly” from pouring into China.

The mob’s code, expressed by a lieutenant who’d rather die that talk, is “Glory to those who put honor over profit. Shame to those who put profit over honor.”

The cops? They debate their “sense of purpose” when they’re not letting Lam and others off, even though they have them in custody after bloody shootouts where policemen have died.

No, they didn’t catch them “red handed” and online, which is much more serious. Apparently.

“I Did It My Way” has one fine martial arts throwdown which stands out among the utterly generic shootouts, which are numerous.

The characters are thinly sketched in, even if the leads manage something approaching two dimensional.

The film reeks of sexism, never moreso than when the mob lawyer deigns to hide his much younger pregnant bride’s (Yase Liu) eyes as bullets and mayhem rain down on them. Hey, she knew what she was marrying into. And she’s been hiding her pregnant smoking from you, chief, in case you didn’t know.

Here, that’s what amounts to a minor sin. Because when everybody on every side (Let’s not forget the Westerners supplying this trade, Colombians among them) is doing it “their” way, there really isn’t any room for judgement, negotiation or any sort of moral high ground.
