Keanu Reeves specializes in one role, and that is The Surfer. No matter how high the wave, or how violent the waters, The Surfer always manages to ride it out. He doesn't choose the wave, or the moment, or cause anything to happen; it all happens to him, and he simply rides it out with this serene look on his beautiful face.
That's what Reeve's career's built on--The Surfer's look. From Bill and Ted to Point Break to Speed to Little Buddha to the Matrix movies, when climax time comes he flashes that look, and all is well. That look has been interpreted as everything from the beginning of a retard's comprehension to a disicple's disillusionment to a police officer's realization (of a bomber's REAL trick) to Enlightenment to a man's epiphany that he is The One. The only thing that varies is the nature and intensity of the wave The Surfer rides, from film to film--from Death to villainous guru to mad bomber to the world as we know it to a worldwide computer. It's his one trick, and his one genius is to build a career out of that trick.
