Really? I found the movie to be a series of several hundred mildly amusing jokes such that any one of them provides a chuckle or even a hearty laugh as a sound bite, but which strung together into a two hour movie were completely devoid of any dramatic elements to prevent the movie from collapsing into monotony. As silly as it was, even Airplane had a dramatic story arc, character development, pacing, etc., which were all terribly lacking in Annie Hall.
Frankly, such aspects were so lacking in Annie Hall, that it helped educate me as how a good comedy must be better than a sequence of funny jokes.
I love both “Airplane” and “Annie Hall”. Both are hilarious, but completely different types of humour.
