As they say, it’s not a bug; it’s a feature. Yes, romantic comedies keep relying on the same elements. All the Jessicas and Jennifers who star, all the quippy best friends, all the cute apartments and makeover montages, all the strolls through the farmers markets, looking through the mounds of fruit, coming home with grocery bags filled with bottles of wine and baguettes, the kisses in the rain, the misunderstandings, the initial antagonism that turns to love, the race to the wedding (to stop it) or to the airport (to keep that special someone from flying away), and all those bouncy pop songs on the soundtrack to make up for the absence of actual lines of dialogue. Why should we hear what people say to each other when they are falling in love when we can imagine it as we bounce along to the music and watch them stroll on the beach and ride bicycles and playfully toss soap bubbles or autumn leaves or pillows at each other?

We don’t go to see romantic comedies in spite of this repetition; we go because of it. Just like we play the same songs over and over, it is the very predictability we find so satisfying. So “Isn’t it Romantic,” starring Rebel Wilson, is as much an affectionate tribute to the romantic comedy as it is a parody of it. In the first scene, the mother (“AbFab’s Jennifer Saunders) of a young Australian girl is telling her that the movie she is watching, “Pretty Woman,” is unrealistic, like all romantic comedies, and, in fact, she says that there is no such thing as love. “In real life, girls like us can’t get that.” (If this reminds you of the “monogamy isn’t realistic” flashback of the romantic comedy “Trainwreck,” buckle up, because the call-outs of other movies are non-stop.)

Twenty-five years later, that girl has grown up to be Natalie (Rebel Wilson) is an architect in New York, cynical about romance and shy about standing up for herself at work. She has an assistant (a terrific Betty Gilpin of “Glow”) who spends all day watching romantic comedies instead of doing her job and a friend zone buddy named Josh (Wilson’s “Pitch Perfect” love interest Adam Devine). When she bangs her head after a mugging in the subway station, she wakes up in the hospital — and the world has been transformed to a romantic comedy, wisecracking gay best friend, meet cute dreamboat, her apartment quintupled in size, her neighborhood all bright colors, flower shops, and cupcakes, “as though a beauty filter had been applied to all of New York.”

At first she resists, but then she decides the best way to get back to real life is to create a happy ending, at first with a handsome millionaire who finds her “beguiling” (fellow Aussie Liam Hemsworth), and then with Josh, who by this time is caught up in his own romantic comedy with swimsuit model/yoga ambassador Isabella (Priyanka Chopra). The film manages to pay tribute to/make gentle fun of films like “My Best Friend’s Wedding,” “Notting Hill,” and “13 Going on 30” while folding in some female empowerment, too. It mostly escapes the failures of the silly “Scary Movie” franchises by recognizing that it is not enough to refer to something; you have to have something to say about it. At a brisk 88 minutes, “Isn’t It Romantic” manages to have something to say, and by the time the happy ending and yet another musical number it will have achieved what all good romantic comedies do — it will leave you smiling, and maybe a little bit hopeful about romance.

Parents should know that this film includes strong and crude language, sexual references and non-explicit situations, crude humor, brief nudity, drinking, a drug dealer, comic mayhem and violence and a mugging.
