The movie is more interesting than achieved: it's the most forthright statement of the transference theme in Hitchcock's work, but it's also the least nuanced.

Even though moments in the picture do have some tension and power, and the whole thing is scrupulously acted by a tightly professional cast, the consequence is an entertainment that tends to drag, sag and generally grow dull. It is not the sort of entertaiment that one hopefully expects of Hitch.

I Confess ultimately reveals itself to be one of Hitchcock’s most successful examinations of the tension between public image and private turmoil.
