I have to say I am in full agreement. While I've liked Citizen Kane and have seen it 3 or 4 times I have always seen it as a demonstration of innovative genius rather then cinematic genius. Vertigo, on the other hand, has fascinated me ever since I saw it on TV as a child. Back then I thought it was just "wow" without any understanding of the psychology involved. In my twenties, I watched it again and realized it was not just about one man's fear of heights. I began understanding the psychology involved. The word "obsession" began entering my vocabulary when I talked about it with friends, while we postulated the differences between obsession and mental illness since this film is about both. I watched it again a few years ago and must say there are times in it when I felt truly uncomfortable most especially the scene where James Stewart dresses up Kim Novak as the dead Madeleine.
This scene creeped me out so badly I almost got up and walked out the room because at that moment I realized just how crazy James Stewart's Scottie had become and like the police officer who falls to his death in the beginning, Scottie has stepped off the roof of reality.
