There’s no getting around the “romance novel with abuse” maternity of “It Ends with Us.” A florist named Lily Bloom, a tall, handsome lover with anger management issues named Ryle (“Rile” would have been too on the nose?), a white knight from Lily’s past named Atlas, carrying her world of hurt on his shoulders?

But the abuse text and subtext of this Colleen Hoover novel resonated with millions of women. And give it to director and co-star Justin Baldoni and screenwriter Christy Hall (“Daddio”). They may have recognized the “Lifetime Original Movie” (a disaparaging term used by male critics, mostly) in their source material. But they lean into it and take their shot at making this the best Lifetime Original Movie they can.

When you’ve got Blake Lively as your heroine and smoldering “Jane the Virgin” veteran Baldoni parlaying his co-starring “villain” role into a directing gig (he got behind the camera for “Jane the Virgin,” and directed “Five Feet Apart” and Disney’s “Clouds” as well), you’re off to a good start.

And if it’s a tad on the leisurely side, that’s “patience” and “respect for the material” and the fans who love the book. If there are far too many musical montages of courtship and life in Boston, too many slo-mo “Their eyes locked” moments, that’s “fan service, “too.

If it’s all heavy on the adoring closeups of our beautiful characters and endless fashion-forward wardrobe changes (Once a “Gossip Girl,” always a…), you go with it.

No, I don’t think “It Ends with Us” is heading towards anybody’s “Movie of the Summer” lists. It’s obvious and slow and cute in all the places you’d expect, melodramatic in many of the others.

But for what it is, it is superbly crafted — from the casting to the kitschy, over-decorated sets and over-dressed leading lady to the editing and the way the performers embrace the nuances of extreme close-up (“soap opera acting”) performances

We meet Lily when she comes “home” to Maine for her father’s funeral, which she abruptly leaves rather than come up with a “Five things I loved about my Dad” eulogy. That’s what’s up.

As Lily, the mayor’s daughter and a child of privilege, moves to Boston and opens up a hip, uncoventional florist shop named “Lily Bloom’s, we put together pieces of her past, told in flashback (Isabella Ferrer is “young” Lily). We see her compassion, offering aid to the homeless boy evocatively named Atlas (Alex Neustaedter) and falling in love with him in their teens.

The flashbacks are folded in as adult Lily is courted by the raking “neuro surgeon Ryle (Baldoni), who turns out to be the brother of Lily’s first employee, affluent newlywed Allysa (Slate) who uses the phrase “my best friend” in a romance novel rush.

The courtship is romantic and sexy as all get out, interrupted by Ryle, Allysa and her husband’s (Hasan Minhaj) goofy hockey fan traditions (onesie pajamas for game night) and Lily’s teasing, aimed at keeping Ryle at arm’s length.

“I’ll…see you around.”

“Will you?”

“No.”

But we know they’re destined to be together. And we’ve seen how they met, with Ryle kicking furniture on the roof above his penthouse apartment. We have to figure that’s a bad omen, and that the adult Atlas (Brandon Sklenar) is fated to turn up in Boston, conveniently as a restaurateur.

The best thing Lively brings to this performance is the confidence of the inutterably gorgeous. She knows she’s a looker, and neuro-surgeon or not, Mr. “I want to have sex with you…Love isn’t for me, lust is nice, though” is going to have to work hard on this “girl you bring home to Mom.”

Baldoni, always unshaven, is the quintessence of “tall, dark and handsome” and “maybe dangerous.” He’s good in a role that he never allows to seem despicable, at least in his own eyes.

And Slate is a nice splash of sunny, warm comic relief, Ms. “Don’t fish where I SWIM, Ryle” to her randy, womanizing brother.

The violence, when it comes, isn’t shocking or over-the-top. It’s on the “Should we file a police report or not?” end of the spectrum.

But Lively plays that with gravitas and mixed-emotions that millions of battered women and their friends will recognize. And the script hides Lily’s hand and her fate better than you’d expect.

It turns out this late summer blockbuster has a lot in common with the blockbusters that preceded it, such as Lively’s husband Ryan Reynolds’ “Deadpool & Wolverine.” Don’t overthink it and you’ll be fine.
