The explanation given is lame. Unnecessary narration by Judd and bothersome title cards also get in the way of things. The story takes all the prerequisite twists and turns, plotwise and emotionally. Girl meets boy and is happy. Girl loses boy and is sad.
Girl almost gets together with boy and is happy then sad.
Girl meets other boy and discovers she is really happy. Every romantic comedy has a gimmick. Jane refers to them constantly and then compares them to the actions she observes in men. For somebody who supposedly went to college, she is sure emotionally immature. Except for the acting, none of the main characters are really appealing.
