A creatively self-conscious comedy that is part real documentary and part, well, something else, Paper Heart begins as an inquiry by artist and comedian Charlyne Yi into the nature of love. Working closely with pal and director Nicholas Jasenovec, Yi travels the U.S. looking for anyone who will talk to her about their experiences with or perspectives about love. Along the way, she meets some wonderful people, including older folks, children, and even a celebrity (Seth Rogen) or two. But nothing shakes Yi's skepticism that there is such a thing as permanent, romantic love until actor Michael Cera (Juno) stumbles into her on-camera life. Shy but curious about one another, Cera and Yi cautiously hook up, troubled by the omnipresence of Jasenovec and his crew but unable to get free of Yi's agreement to allow everything to be filmed. The very pressure under which they try to make their simmering relationship work becomes the test Yi needs to believe that love is real--or, at least, cleverly scripted. It's hard to know exactly where the line is between documentary and fiction in this film, but in a way it doesn't matter. A point or two is made, and the audience gets to enjoy Yi's cardboard-cutout puppetry.
