This is a set that contains some but does not contain all, of Hitchcock's movies Depending on what you consider his best movies to be, this may not contain your favorites. Nor do each of the movies have perfect video and audio. The 15 movies included in this collection (each on separate discs) are Saboteur, Shadow of a Doubt, Rope, Rear Window, The Trouble With Harry, The Man Who Knew Too Much, Vertigo, North by Northwest, Psycho, The Birds, Marnie, Torn Curtain, Topaz, Frenzy, and Family Plot.
There are a lot of reviewers on Amazon pissed at Universal for not restoring all of them. I am never one who expects movies that old to look as good as something made today, so the grain and glitches in the video that you occasionally see do not bother me all that much. In fact, some movie purists enjoy seeing grain and imperfections that are common to movies that were shot on film. That said, some movies have a wonderful restoration (e.g., Sabotuer), others have a good to very good restorations (e.g., The Birds, Rear Window, and Psycho), while others (e.g., Family Plot) have a very bad transfer. The films that have been restored like Rear Window do look great, however.
I also think the extras that you get on each movie are very good. The documentaries which have interviews with the remaining stars, filmmakers, and Hitchcock family members are very good. I don't really know how this compares to the DVDs that are already out there. You probably want to research whether this will be that much of an upgrade to what you already have if you own any of the movies included here. That said I do like the collection and am very happy with it.
