The Criterion Channel is the carefully curated streaming service that was launched in the wake of the long-lost FilmStruck. Devoted exclusively to classic movies, famous art films, and world cinema, the service also features extensive commentaries from cinema scholars, enthused video essays, and all manner of tools to equip both outsiders and longtime devotees to the extended world of film. And, just to sweeten the deal, The Criterion Channel also is home to many, many enthused introductions to their films, some of them from recognizable and beloved nerd icons.
