I still haven't seen any episodes of Lost, but I'm sure I'll get it on DVD or download someday.
My friends who do watch it were ambivialent about the finale, but they LOVED the commercials for Target that ran during the braodcast. In one, a pig runs through the jungle, and then we see the onscreen words: "Barbecue Sauce $2.39." In another, we see the Smoke Monster on the beach, and then the words "Smoke Detector $7.99." So that was entertaining, at least.
