While the movie Inception has certainly invited discussion about dreams and even an interest and analysis of viewers’ own nightmares, you may recall that in the film, the motivation for entering the dream world is the recognition of the impact of a persistent idea. As Leonardo DiCaprio (Cobb) forebodes in the opening of the film, “What’s the most resilient parasite? An idea.”
In the movie’s narrative, hidden beneath the scaffolding of dreams and driven by the confusion of dream and reality is an idea that ultimately destroys Cobb’s wife, his relationship with his children and possibly his ability to discern reality – depending on your take of the ending.
Recognizing that media both reflects culture and is shaped by it, this film raises the question, “Can a persistent negative idea threaten a relationship?” Yes.
