Inventing the Abbotts explores several themes that are relevant to the adolescent experience. One of the primary themes is the struggle for identity and self-discovery. The Abbott brothers and the two young women are all navigating their way through adolescence, trying to figure out who they are and where they fit in the world. The film also explores the theme of first love and the complexities of romantic relationships. The relationships between Edward, Bunny, and Mary are multifaceted and nuanced, capturing the intensity and uncertainty of first love.

The female characters, Bunny and Mary, are also well-developed and complex. Bunny is a free-spirited and artistic young woman who becomes infatuated with Edward. Mary, on the other hand, is a more reserved and traditional young woman who is drawn to Edward's charismatic personality. The character development of the Abbott brothers and the two young women is crucial to the film's narrative, as it explores themes of adolescence, first love, and family dynamics.

The film is set in the 1950s in a small town in the Midwestern United States. The story revolves around three Abbott brothers, Edward (Ian Somerhalder), Simon (Jeremy Davies), and Jason (Joshua Jackson), who live with their widowed father, Lloyd (Tommy Lee Jones). The narrative is presented through the eyes of two young women, Bunny (Joey Lauren Adams) and Mary (Amy Locane), who become infatuated with the Abbott brothers. The film's non-linear narrative structure adds complexity to the story, as it jumps back and forth in time, revealing the characters' past and present experiences.
