Matthew has written a self-help book about getting over old love by forgetting the past and deciding to focus on future love. Kirstin, who is a therapist, is dragged by her friends to one of Matthew's lectures where she harshly criticizes his theories. This is picked up by a TV channel, and soon they find themselves in a TV studio debating each other. Before long, they are on a tour across the USA where they meet in various TV debates. Meanwhile, Matthew has to deal with his ex and their daughter while becoming increasingly captivated by Kirstin.
This movie is a good romantic film, even though it might get a bit too sugary sweet at the end. I was worried for a long time that it would take the wrong path, but it turns out well.
