Everyone is aware that the romantic comedy genre has turned into the biggest cliche in Hollywood over the past few years. However once in a while, there's at least one movie a year that attempts to do something new with the fledgling genre, and surprisingly ends up succeeding with it's innovations. The most important example of that kind of film is 2004's "Eternal Sunshine of the Spotless Mind," which not only added a science fiction/fantasy twist, but also now stands as one of my favorite movies of all-time, too.
