First, the elephant in the room is the narration. I am watching this documentary and while I do enjoy the discussion of the masters point of view on his films which is fascinating, I cannot help being manipulated somehow using the masters voice taking words obviously not written by him as if it were. For me, it is very distracting. I really been written or added to by a screenwriter in the 21st Century. Alfred Hitchcock has been dead since 1980 and there have been many articles, documentaries,filmmakers,actors, cinematographers, artists, books and scholars that have had points of view of what certain scenes meant or how they should be viewed. The shower sequence in the film, "Psycho " alone has two masters, Alfred Hitchcock and Saul Bass. This documentary answers many questions but at the same time is glaring in it's overuse of the impressionist voiceover. For many in college studying film this gimmick likely will not bother them. It is likely they have never experienced a Hitchcock film in a revival theater being projected on the big screen. For a generation watching these films on a small screen via streaming, blu ray, dvd or video it will suffice. If it's information you seek, this is filled with it. Mark Cousins has made an enjoyable film for the 21st Century. For those over a certain age who have watched the master, read or heard his interviews with Truffaut or Bogdanovich listening to the impressionist rather than hiring an actor to be a narrator rather than the master himself, I found the film a bit to distracting to give it the full due it deserves.
