Not being familiar with Wendy Wasserstein's work, I didn't feel comfortable commenting on it in terms of her TV contributions. I knew who she was, what she wrote, what her plays were basically about, but I never saw them to familiarize myself with them.
So now Virginia Heffernan has done an excellent job of looking back at the work Ms. Wasserstein did on TV since 1979, with adaptations of her own plays as well as new versions of stories by the likes of John Cheever. You can read it here.
