Enjoying this wondrous wisp of a something is easy, describing it is hard. Luckily, Charlyne Yi is an enchantress. I'd follow her anywhere. Maybe you saw her doing stand-up or acting in Knocked Up. Here she is playing herself, sort of. She's making a documentary about love. Since she doesn't believe in it, she interviews people who do. Then she meets Michael Cera, who is playing himself, sort of, since he's Charlyne's real-life boyfriend, maybe. Wait, there are puppets and other visual aids. And you should know that director Nick Jasenovec is played by actor Jake Johnson. Paper Heart won Charlyne the screenwriting award this year at Sundance. Her background is Filipino, Spanish, Korean, Irish, German, French and Native American. That won't help you figure her or love out. But that's the point. Maybe.
