In the end, however, it's just a nail-biting thriller that - now over sixty years old - still reigns as one of the absolute best of its genre. It manages to focus on family ties and the struggles within the family itself while it also juggles the whole theme of an outcast family member. The entire film is taut and suspenseful, well-filmed and realistic. The ending of "Shadow of a Doubt" is classic Hitchcock and some of the best stuff he's done. She begins to become suspicious of her uncle as he becomes more suspicious of her own awareness. A teenage girl, overjoyed when her favorite uncle comes to visit the family in their quiet California town, slowly begins to suspect that he is in fact the. Charlie acts oddly and, at times, violent. His niece - who loves him and sees him as a sort of perfect role model - at first is excited that her Uncle Charlie is coming.but then things start to get strange. Left stranded and pursued, he decides to move in with his brother's family. Joseph Cotten plays Charlie, a crook on the run from the police. "Shadow of a Doubt" may only be listed as #181 on IMDb's "Top 250" list, but in my opinion it far outweighs some of the films higher up on that list and is one of Hitch's very best films.
