This was the worst season ending, if not the worst episode, of any comedy I've ever seen. First, a joke was made about Susan possibly dying in a plane crash. Hey writers, ever heard of ValuJet? Really poor taste.
Then, Susan DOES die. OK, we all know George wanted out of the whole thing, but death by toxic glue from the wedding invitations? While I see the irony, couldn't they come up with a funny way to get rid of her?
I'm not sure if the regular writing team was locked in a closet somewhere, but if so, let them out soon!
