Critics Sentiment
Jo screams to prevent assassination during cymbal crash at concert

The film transforms from slow character development to masterful suspense when Bernard's murder occurs, jumping from a modest 7.2 to 8.5 as the thriller elements take hold.
Critics found this Hitchcock remake a professionally crafted but uneven thriller that starts slowly with overlong setup sequences before building to genuinely masterful suspense. The Albert Hall assassination sequence earned universal acclaim as a wordless masterpiece, while Day and Stewart's emotional scenes, particularly the sedation sequence, drew widespread praise for their performances.
