Marry Me

She sings, she dances, she melts hearts with a single wink or glance. Legions of Jennifer Lopez fans will find plenty to appreciate in Marry Me, which showcases J-Lo in all her multifaceted glory.

However, while she’s working within her comfort zone, Lopez’s charisma alone can’t rescue this assembly-line romantic comedy that’s more calculated than heartfelt.

She plays Kat, a global pop-music superstar who is poised to marry her boyfriend, Bastian (played by real-life singer Maluma), as they perform their hit duet for their 20 million viral followers.

On the big night, rumors circulate the Bastian has been cheating, and Kat instead impulsively picks out Charlie (Owen Wilson), a divorced math teacher who’s only in the concert crowd to score points with his young daughter (Chloe Coleman). “This is a manic response to an insane situation,” explains her exasperated manager (John Bradley).

Everything Kat does is in the public spotlight or subject to the whims of corporate sponsors — to which Lopez can probably relate — and that creates friction with timid Charlie, who of course has a flip phone and can’t understand why a nationally televised interview should upstage practice with his “mathalon” team.

Their marriage becomes a temporary, mutually beneficial business arrangement until her public embarrassment subsides. But privately, their vulnerabilities eventually create a deeper bond that could lead to something more.

From the contrived premise to the exaggerated rationale for either character accepting such an agreement, the whole thing feels detached from reality, which in turn significantly diminishes the incentive for emotional investment.

The screenplay, which apparently was adapted from a graphic novel, struggles to provide dramatic texture as a half-hearted satire about the fickle nature of celebrity and personal brand-building in the social-media age. It also feels muddled in promoting a progressive outlook toward defining how love fits into marriage.

The film’s modest charms are courtesy of the offbeat chemistry between its stars. There are some amusing highlights, such as a sequence in which Kat visits Charlie’s classroom during a math class and interacts with the cute kiddos. Some of the songs, written by Lopez and Maluma, hit the mark.

But the more the central relationship progresses, the more the film directed by Kat Coiro (A Case of You) settles for predictable opposites-attract cliches. Fate might have brought these two lost souls together, but you can leave them before the altar.

Rated PG-13, 112 minutes.
