“New Year’s Eve” is the second in a remarkably shallow series of holiday-themed, celebrity-stuffed confections from director Garry Marshall and screenwriter Katherine Fugate, following their 2010 “Valentine’s Day” collaboration.

Many of the elements are the same as they were for “Valentine’s Day,” just moved back on the calendar a few weeks, with the script again weaving together a dozen or so plot lines that crisscross a holiday prone to sentimentalizing.

Though it’s pure, rosy fantasy on screen, this is cynical, paint-by-the-numbers entertainment, sold with a gaggle of stars spread across its movie poster like a telethon lineup.

The threads of romance emanate from — where else? — New York’s Times Square. Hilary Swank plays a character running the ball drop festivities, at which a famous rocker (Jon Bon Jovi as “Jensen”) is to perform, and where various police keep watch, including one played by Chris “Ludacris” Bridges.

Katherine Heigl plays a chef catering a pre-party featuring Jensen, who happens to be her ex-boyfriend. Her sous chef is Sofia Vergara of “Modern Family.”

Abigail Breslin, now a teenager, is hoping to join her friends in Times Square, but her mother (Sarah Jessica Parker) won’t let her. Jessica Biel, with husband Seth Meyers, is going into labor, competing for the new year’s first baby against a rival couple (Sarah Paulson, Til Schweiger).

Michelle Pfeiffer plays a meek office assistant who quits her job (John Lithgow plays her record-label executive boss, a good bit of casting that should have spawned laughs) and hires a courier (an ultra-confident Zac Efron) to help her accomplish a list of resolutions.

Ashton Kutcher, as a bearded grouch, gets stuck in an elevator for hours with backup singer Lea Michele. (I crossed my fingers that bathroom needs would spoil their budding romance, but alas.) Most incredulous, perhaps, is the pairing of nurse Halle Berry and dying Vietnam veteran Robert De Niro.

En route to love and new beginnings, the many characters run around familiar New York tourist attractions and pair off predictably.

None of the characters are more than cardboard clichés, but the cast is likable and pretty enough that most are able to swallow the pallid dialogue without causing inadvertent laughs.

The cameos keep coming until the end, with even Mayor Michael Bloomberg dropping by. After all, this is as much an ad for New York as it is a movie.
