All of this! I'll preface this with the disclaimer that I haven't read the book yet. The reason why I love the movie so much is how much subtle menace there is lurking behind every scene. I like to show it to people along with Gaslight and Suspicion as a way to demonstrate how emotional abuse can wear many faces. (You can argue with me about Suspicion if you like but I think it was a shitty, manipulative, emotionally and financially abusive relationship and the ending of the film wasn't happy in the least.) Keep your wife isolated and friendless, fly into a rage whenever she relaxes and tries to please you, mope sullenly and be uncommunicative and leave her wondering just what she's done wrong. Oh sure Max, you love her all right.

Also it's why "The Screaming Skull" remains one of my favorite MST3K episodes. Someone tried to staple Rebecca and Gaslight onto a tepid horror movie, and failed in such a deliciously bad way.
