Apparently this was conceived as one long do entary (900 minutes), but it's presented on Netflix as fifteen one-hour episodes, each thematically and/or chronologically organized. It's narrated by its director, and Irish film critic, and so far the narration is a bit... odd to listen to, but he provides a very interesting look at cinema. I find myself appreciating what he has to say even during the times I don't necessarily agree with his point or how it's being made. Perhaps most interesting about this do entary, compared to other film/film history do entaries I've watched, is that there is a very strong and intentional desire to avoid looking solely at cinema in the Western world or through a Hollywood-centric point of view. I haven't watched all the episodes yet, so I can't speak to their success, but I've thoroughly enjoyed what I've watched so far and imaging other movie nerds will, as well.
