A clever-enough conceit, engaging leads and a masked villain of the Jason/Michael Myers/”Scream” variety might be enough to recommend “Heart Eyes,” a “rom com for Valentine’s Day” for the splatter film crowd.

Hey, everybody needs a “date movie,” right? It’s not like they’re making “His Girl Friday” (seen in a pop-up drive-in here) these days.

But the conceit isn’t as clever as the filmmakers’ think. And while the script offers a few scattered chuckles, they’re mostly of the if-the-heroine-shouts “LEAVE US ALONE” and “You’ve got the WRONG people!” in the hopes that the masked mass murderer might leave her and her date (“It’s NOT A DATE! We’re NOT a couple!”) alone.

That puts all the pressure on Olivia Holt (TV’s “Cloak & Dagger” and “Cruel Summer”) as Ally, the clever ad campaigner who thought using bloodied dead lovers from history for a Valentine’s Day TV commercial pitching selling engagement diamonds, and “Scream” franchise alumnus Mason Gooding and a lot of not-as-clever-as-“Saw” bits of slaughter.

They can’t carry this still-warm corpse across the finish line.

Ally (Holt) has a strained “meet cute” with Jay Simmons (Gooding) before she figures out he’s the marketing genius brought in to “save” her brutally tasteless and now awfully timed “doomed lovers” campaign for Crystal Cane (Michaela Watkins, drawling and vamping) Jewelry.

The “timing” thing comes down to a Seattle visit by the annual Valentine’s Day murderer, a spree killer nicknamed “The Heart Eyes Killer,” aka “HEK” by the national media. Boston one year, Philly the next, and now the masked ghoul with heart-shaped goggles that light up with when he switches on night-vision has hit the Pacific Northwest.

He targets loving couples, like the vineyard duo who stage “his” proposal at sunset, re-doing it when their photographer misses the shot.

“I will END you” threats from the groom, “on Yelp,” set the tone. This is a comedy. These pitiless, pointless killings are played for laughs. There are a few interesting, possibly funny and twisted ways to do somebody in at a winery. None of them involve a machete or crossbow, our killer’s weapons of choice.

A business dinner that involves a staged kiss puts a target on Ally and this Jay fellow’s backs. And they spend the rest of Valentine’s Day night dodging death and staring, incredulously, at two half-assed cops on the case, “Hobbs” (Devon Sawa) and “Shaw” (Jordana Brewster).

“Like the movie?” “Never saw it.”

The narrative stumbles along with injuries and escapes and one predictable predicament after another, with shallow discussions of “kink” and glib treatments of death and the way those who survive “honor” acquaintances, part of a dinner party of four, who have just been murdered.

“You kept the reservation?” “To honor them…”

Holt is perky and makes Ally properly put-out at this killer’s insistence on pursuing them even though “We’re NOT a couple.” Gooding brings a little less — comedically — to the party. He’s not alone. Nobody here has great comic chops.

The goofy tone is maintained, start to finish. But that finale is the biggest dud among the various clunky set-ups that don’t produce anything funny or scary or romantic.
