Remember when film criticism relied upon a simple “Thumbs up” or “Thumbs down”? This was an extraordinarily powerful way to gauge a movie’s quality and it was through this method that film critics and journalists ever since have adapted to their own ways of judging cinema. Roger Ebert was one of the pioneers of the “Thumbs up” approach and he was not just a talented writer and critic but a force for good in American pop culture. His intelligence and supreme wit have made him a cultural icon and the new documentary Life Itself beautifully sums up the man’s life.
