Annie Hall is refreshing because it showed an astonishing leap in creativity, exploration, and cinematic curiosity from Allen's previous film, the very funny but flat Love and Death.
Previous movies such as the mock Russian literature epic "Love and Death" are funnier but are only really a sequence of gags.
After skewing Russian literature (Love and Death), political leaders (Bananas), and future nostalgia (Sleeper) in broad comedies, it was as if Woody said, “Okay, you’ve seen that I can be funny, now it’s time to get to know me a little bit.”
The comic level of Annie Hall is not as high or frantic as in Allen's Sleeper or Love and Death.
A culmination and a transition, refining the spray-gun approach of Sleeper en route to Annie Hall, and, like Twain's The Innocents Abroad or Jones' What's Opera, Doc?, an act of artistic debunking that reassures the importance of art.
