Is KNOCKED UP a great film? Yes, and no. To me, a great film requires astute direction as well as writing. Apatow is an astoundingly adroit observer of human behavior, but for now, he's a firmly commercial director. Which is to say, there's nothing particularly daring here. But I'll keep our fingers crossed. In the end, KNOCKED UP is that rarest of birds, a summer film (and a monster hit) about the vagaries of human interaction, the twists and turns of fate that lead folks to embark on long, difficult journeys. The best news of all may be that honest movies about human behavior can still offend. At the showing I attended, about six or seven elderly women sitting in the row behind me (chatting away throughout the film) rose en masse and exited the theater as Ben's roomies launched into a spirited discussion about bowel movements.
