For all we know, cyborgs may be making movies 50 years from now and all the critics will be AI. However, if things stay as they are today and people care about film stars of the past and want to study their careers,Jennifer Lawrenceis going to be someone people care about and “No Hard Feelings” will be regarded as a key movie.

称之为电影看起来非常的关键sive, if you look at “No Hard Feelings” as a coarse comedy, which it is. Lawrence has appeared in much better movies, from “Winter’s Bone” to “American Hustle” to “Don’t Look Up.” And yet I doubt she has ever had such an ideal showcase. It’s hard to imagine this film even working with anyone else in the central role.

Basically, “No Hard Feelings” is everything you like aboutJennifer Lawrence, brought together in one movie and then magnified: her down-to-earth irreverence, her comic timing, her idiosyncratic naturalness and her unexpected sensitivity.

There’s also her full-throttle fearlessness, on display here in a scene where she goes skinny-dipping and some teenagers steal her clothes, so she comes marching out of the water completely naked and attacks them. It’s an example of an actress matching the courage and intensity of the character she’s playing.

“No Hard Feelings” takes place in Montauk, Long Island, a vacation spot where the summer brings together wealthy visitors and hardscrabble townies who resent the annual invasion. Of course, Lawrence is one of the townies, Maddie. Her house is totally paid for, but she might lose it anyway because she has fallen behind on her exorbitant property tax, which goes up every year. (In New York, they don’t have Prop. 13.)

不顾一切地抓住她的房子,无法make extra money as an Uber driver because her car has been repossessed, Maddie is hired by a pair of wealthy, overprotective parents (Laura Benanti and Matthew Broderick) to “date” Percy, their shy son. They want her to build up his confidence by having sex with him and, in exchange, they’ll give her an almost-new Buick Regal.

What you might expect from the movie based on that premise is a lot of rude, abrasive comedy. There’s plenty of that, to be sure, but a welcome aspect of the screenplay is that it doesn’t push the characters to act like typical characters in a raunchy comedy. Instead, once the situation and the characters are off and running, the movie unfolds in an unforced way, going in unexpected directions.

Percy (Andrew Barth Feldman) becomes almost as important a character as Maddie. Though at first he just seems like a nerdy disaster, one who has been made to fear everything by his overly cautious parents, we begin to see the situation from his angle as well. Yes, he’s naive and he doesn’t know anything about life, but he’s not an idiot. So when this woman in her early 30s starts coming on to him in an overt sexual way, he can’t help but become intimidated and suspicious.

As a result, what appears to be a high-concept comedy, one about nothing besides pulling the maximum number of laughs out of a promising premise, emerges as a character-driven story about complicated people.

At least that’s one way of looking at it. You can also look at it as a comedy being guided entirely byLawrence’sscreen personality — and that way she has, in role after role, of moving from harshness and strident self-assertion to genuine warmth.
