Ok I just saw the pilot for Under the Dome. Truth be told I kept flipping between that and Earth Underwater which was somewhat more interesting. I never read the book, but this seems like the usual King fare.
1. There is a Meth lab in town, hence the Propane deliveries.
2. The Dome was created by friendly aliens to save them from the meteor shower/asteroid collision/falling comet.
3. The town councilman was partnered with the guy Barbie killed.
4. The sheriff knows about the councilman being a crook.
If there is nothing more interesting on, I'll catch episode two next Sunday.
