Greatest Science Fiction Movies of All Time

101 Sci-fi movies ranging from the beginning of cinema to the present day that IMHO represent the best the genre has to offer. Some are examples of cinematic art, while others are representative of the times that they were made. I've made an effort to cover all of the decades, and have made some hard editorial choices to keep the list at 101. To answer to most pressing question - If I had to choose only one, it would still be "2001: A Space Odyssey ".
