“Cutesie” does battle with “sentimental” in the feather-light romance “Love at First Sight,” basically a Netflix-financed 90 minutge excuse to pair up Haley Lu Richardson with Ben Hardy and have them lose each other in rainy, wintry London.

It’s a romance-novel of a script filled with fate and coincidences, mathematical probabilties, attraction and tragedy, explained away by an omniscient and omni-present (in many guises) narrator.

“Cute” becomes “cutesie.” But after an insipid and unamusing start, “Sight” rallies as it takes on more serious subjects, giving Richardson (“Five Feet Apart,””White Lotus”) and Hardy (he was drummer Roger Taylor in “Bohemian Rhapsody”) a chance to shine.

“Hadley” is often late, which is how she misses her pre-holiday flight to the UK from JFK. But that’s OK. Because that fellow who just offered hapless Hadley his phone-charging cord is easy on the eyes.

She’s in college, he’s studying statistics and “maths” at Yale, and after that missed flight, coincidences by the score align to put these two together on the same flight, on the same row, an hours-long “first date” that includes two means and “a cheesy rom-com.”

Which airlines carry Netflix? I forget.

They get separated in London, with her dashing off to her father’s (Rob Delaney) second wedding and him off to a public family event with theatrical mum (Sally Phillips) and dad (Dexter Fletcher).

But at every turn, there’s our narrator, giver-of-odds and fate-intervenes queen, played by Jameela Jamil as a flight attendant, customs officer, bus driver, wedding bartender and several other costumes.

She’s forever reciting stats about how many people are on plane, how many wedding guests spoke, wore hats (“48”) or were moved to tears (31%).

Veteran TV director Vanessa Caswell fights a losing battle with “cloying” much of the time. But the emotional stuff resonates, the leads are charming and engaging and the setting is London, where no one in her right mind would ditch bridesmaids heels and go barefoot in the rain a couple of days before Christmas because the average temperature, according to statistics, is 48 degrees.

And if I’ve done my job right, the praise and pounding of this innoccuous picture have balanced out to a statistical “mixed bag” review. Which “Love at first Sight” most decidedly earns.
