The action was great, the actors even better, special effects were good, production values were top notch, and I'm throwing a serious shout out to the stunt performers. Everything worked except the script.

I loathe plots that rely on the stupidity of the protagonist because the scriptwriter couldn't be bothered to find another way to move the plot. When that stupidity is mired in mach 10 sexism I'm even less forgiving. I watch enough kdrama that I'm resigned to the sexism that pervades its stories, but even with that built in allowance, this script leaned too heavily on bimbo stereotypes to drive the action.

I won't spill anything that will spoil your experience if sexism and stupidity aren't deal breakers for you, and sadly they aren't for many people - that's why there's so much of it, but I will point out a few of the details that had me trotting back to my watch list for something more worthy of my time: A trained covert agent of the a Korean National Intelligence Service hides her multiple fake passports and IDs in her underwear box, because who would ever rifle through a woman's lingerie to find evidence? She keeps her gun unloaded, presumably because she's never heard of a gun safe, so it's never ready when she needs it. No matter how many times this recurs, her behavior doesn't change. It seems even superstar Bae Suzy did not have the clout to plead for a production that didn't make her character an idiot.

And, yes, I'm calling it sexism because, unless it's slapstick comedy, a script for a male agent would not have his go-bag tossed in with his underwear, his gun unloaded when he needed it, or his hands shaking too badly to load that gun; nor would he be the only character in the series that didn't qualify for at least a semi-automatic weapon. The script wouldn't have a male agent hand off his weapon to an untrained civilian to do the bang-bang stuff, even if that civilian IS a manly Mary Sue who could do everything but don a cape and fly - although he did some impressive parkour that was close to flying. Finally, I'm pretty sure the scriptwriter would not have a male agent advocate to flee the county where ALL the known suspects are because "our lives are at stake," like that's not in the job description.

The sexist stereotypes and dependence on stupidity are not, by far, the only saboteurs of a script that stretches credulity on so many levels, but if you're still undeterred, those things probably won't bother you either.

The actors, all of whom delivered on their performances, deserved better than they got. So did the viewers. Life is short and there are too many wonderful kdramas to waste time on a contrived story line with a Swiss cheese plot. I dropped the series after three episodes.

I won't hesitate to find other dramas these actors are in, because every one of them was excellent in their roles, but I'll avoid the scriptwriters like they're patient zero for the plague.
