Charlyne Yi, a musician and comedian, plays a fictionalized version of herself. In the documentary, she states that she has never been in loe, and that she doesn't quite believe in love either. She sets out to interview people (scientists, couples, etc.) trying to learn more about love. Along the way, she meets Michael Cera, who is also playing a fictionalized version of himself. They start a relationship and have the deal with it being part of the documentary.
This hybrid documentary (hard to tell what has been fictionalized) explores interesting topics about love and relationships. I found it interestig, albeit a bit slow. Fans of Yi's type of performance may enjoy this a bit more. In the end, you kinda want to wack her in the head and yell, looks what's in front of you. Seems to work! I also loved the puppet stories!
