Jaws. The Sixth Sense. Raiders of the Lost Ark. The Shawshank Redemption. Just a handful of movies that define cinema's existence. They thrill and entertain, are flawless in technique, and are powerful enough for the viewer to worry for their characters, or shed a tear for them. Well, Gravity just added to that list of masterpieces. A simple story, flowing with originality, following a single character in peril, in the vastness called space. Its script, acting, cinematography, editing, and soundtrack, make this a study in perfection. My other favorite movie of 2013 just found a strong competitor.
