The writer, director, and actor in question is Cooper Raiff, who plays 22-year-old Andrew, a recent college graduate who has moved back home to good 'ole New Jersey—Livingston, to be exact (shout out to my NJ pals). Like every recent grad without much of a plan, he sits around for a bit, ponders life, and then finally decides that he needs to get a job. Naturally, he takes a gig at Meat Sticks, a gross-looking (and sounding) restaurant within a mall. Andrew's demeanor, though, doesn't resemble a person miserable at his job and in his current situation in life—he's the epitome of "when life gives you lemons, make lemonade," but not in the obnoxious way that you're probably imagining.
This dude is so likable, sweet, funny, and kind that it makes you almost expect that he will eventually flip on a dime and reveal that he's actually a terrible person at some point—but that doesn't happen. Andrew is just a genuinely good guy trying to figure out his life, and maybe some people will find that premise boring, but the way this film frames it kept me hooked the entire way through.
While he's still working at Meat Sticks, Andrew falls into another venture, though this time it's purely by accident. While attending a bar mitzvah with his 13-year-old younger brother, David (Evan Assante), Andrew becomes the de-facto party-starter as the shindig has a lame DJ and a lack of dancing guests. By the night's end, he's got a flock of Jewish mothers begging him to host their children's bar mitzvahs, which he ends up pursuing as a sort-of career.
Though he made multiple business connections at the bar mitzvah, Andrew also met Domino (Dakota Johnson) and her autistic daughter, Lola (Vanessa Burghardt), at the party. Domino's mysterious allure brought him over to the pair's table, where Lola was solving an extremely advanced Rubik's Cube with (what looked like) a million pieces in it. His task at hand? To get the pair up and dancing, which he successfully achieves after a little convincing (and with a $300 bet on the line).
The main plot revolves around Andrew's day-to-day life, but Lola and Domino are quickly mixed into things as he starts babysitting for Lola and after Domino makes an advance on him. Though nothing ever goes very far between the two, he becomes attached to the pair and later has to face a new reality as he starts to forget about his own life.
