Two limitations of Hitchcock's art
from Robin Wood, Hitchcock's Films Revisited

1. Hitchcock the showman-entertainer makes compromises against Hitchcock the artist: "a reluctance to allow certain disturbing implications to be fully explored. . . [His films can arouse] complex and disturbing emotions, . . . and then evade their own implications by a sudden simplification."

2. The relative weakness in Hitchcock's art of a normative impulse. . . . His work typically equates 'normality' with a bourgeois life in whose values the creative side of him totally disbelieves but to which it can provide no alternative."
