In my opinion, this is the best of Hitchcock's movies. Though it does sometimes drag, particularly in the final forty-five minutes or so, it draws a great deal of strength from the two leads - Teresa Wright, who avoids the "terrified innocent" trap and makes Young Charlie into a courageous and convincing heroine, and Joseph Cotten, who, as always, excels. Few actors could portray Uncle Charlie's combination of charm and all-consuming evil as well as Cotten, and his performance, inexplicably snubbed at the Oscars, is the single greatest aspect of this fine film.
