Since the mantra is "Pink stars falling in rows" one might suppose the image is of meteorites falling, thus the dome was constructed by alien powers to PROTECT the town from a future cataclysm from the skies. They made another reference of the propane related to drug production Monday night. But it is sadly true, so many of these subplots are totally generic and don't connect to or rely on the dome in any way. And the dome just sits there and doesn't add any new twists week after week. Lost always added new twists and clues, Jericho offered new info and clues and such every week. The Dome...just sits there. But it's Summer and nothing else is on! And that redhead and the shelter chick are hot... That super annoying liitle LA teen bee-yatch is NOT. And the shoehorning in of the achingly politically-correct lesbo moms is utterly gratuitous and insufferable. Where's my FF button??
