I have seen about a third of Hitchcock's films (and that is a lot, more than a dozen), and Shadow of a Doubt was the first one I disliked. I thought the story and characters were uninteresting. I felt no suspense, except for maybe the last ten minutes. The acting was decent, but not great. I like Joseph Cotten, but he didn't do anything particularly noteworthy here. I liked Teresa Wright, too. I could tell she was a fine actress, but I just didn't like her character. The two younger kids and Hume Cronyn and Henry Travers are a really funny pair, too. Overall, though, Shadow of a Doubt didn't capture me like other Hitchcock films. It's my least favorite so far. 5/10
