The very sweet teen romance written and directed by Jon Kasdan (son of filmmaker Lawrence Kasdan) is disarmingly honest, with characters that feel so real there isn’t the hint of artifice.  Centered around two teens who meet by accident, become friends, and each decide to give up their virginity to the other, this film will leave you with a warm, gooey feeling that makes it a worthwhile viewing experience.

Aubrey Miller (Britt Robertson) is a junior in high school.  Leaving a party, she sees Dave Hodgman (Dylan O’Brien), a senior at a different high school, rehearsing a declaration of love for his longtime friend, Jane (Victoria Justice).  In spite of herself, she coaches him on how to do it right, explaining several times that she has a boyfriend and that she hates public displays of affection.  When the party gets busted, he walks Aubrey home and they talk about themselves and what they want to do with their lives.  At the door, she invites him inside and he is blown away by the collages that fill her bedroom.  They have some wine and end up falling alseep on the floor curled up together.

The next morning, they are awakened by a knock on her door.  Panicked, Dave spills a wine glass on his way out the window.  Her parents (Joshua Malina and Christine Taylor) lecture her about drinking, but Aubrey convinces them that its better for her to be drinking at home than at a party or driving.  Through friends, Dave is able to get her home phone number and calls her up, wanting to see her again.  She tells him that she’s going to see a movie with her boyfriend, Ronny (James Frecheville), an older guy who is rather obnoxious.  After the movie, one of their friends invites them to a party at her parents’ house and they all go.

During the party, Ronny tells Dave that he is going to have sex with Aubrey later that night and Dave is depressed that her first time should be with such a putz.  He gets some time alone with Jane, but finds that he is no longer interested in her.  Driving around on his own, he gets a call from Aubrey, who has broken up with Ronnie.  He picks her up and they each reveal that they have feelings for the other.  At her door, they kiss passionately.  The next morning, they go out with his little sister, Stella (Maggie Elizabeth Jones), who approves of their relationship.

Aubrey finds out that her parents will be out for the evening, so she invites Dave over.  Although they are passionate at first, when Aubrey gets a condom for him, everything slows down and they both become extremely nervous about having sex for the first time, which leads to an unfortunate experience.  Afterwards, they are both depressed and when he leaves, she tells him that she will call, but they both have the feeling that it is over.  Each waiting for the other call, they obsess about their feelings for each other.

Eventually, as she prepares to leave for school, Dave shows up.  Once again, he’s been rehearsing what he wants to say to her, but it comes out simply: he likes talking to her and he wants to keep talking to her and maybe they can figure out what happens next along the way.  She asks him for a ride to school and they talk about maybe doing everything better in the future.  In spite of her hatred of public displays of emotion, she says to hell with it and kisses him passionately outside her school.

There are several reasons why the movie is successful.

One of them is Kasdan’s script, which is so incredibly simple that it really tugs at the viewer’s heart.  Many script writers of teen romances try to complicate the story by throwing in all kinds of unnecessary complications, but Kasdan relies on being a teenager as all the complication required and it works amazingly well.  His direction is also simple, very clean, with lots of long two-shots where the actors are allowed to carry the story without any gimmicks.

The other reason for the movie’s success is the performance of its two leads.  Dylan O’Brien gives us a character who is incredibly innocent, who wants so much to be in love that he targets his best friend, without realizing how different they are.  Britt Robertson creates a character in Aubrey who sees the world through cynical eyes, but ultimately wants nothing more than to be with someone who cares about her.  They are both rock-solid performances, completely believable, and ultimately very likeable, creating terrific chemistry together.

This film is short, simple, very well-made, and very heartfelt, with just enough comedy to offset the deeper emotions that it evokes.
