Decent first episode. I've never read the books, so I'm judging the show on its own terms.
At the moment the leading character appears to be the guy named "Barbie". We start the episode with him burying the dead body, I suppose we will find out more about over the rest of the season.
Big Jim and Duke looked to be the political part of the show, until something exploded in Duke's chest. Ow. Hopefully he will recover since I like the actor that plays him. I have a feeling Big Jim might become a bad guy. There was something shady about the character throughout the entire episode.
Angie and crazy Junior look to be the silly teen plot that plague shows like this. But I will wait and see if it actually goes anywhere.
The rest of the characters didn't make much of an impression.
I thought the premise was interesting, the effects for the "dome" covering the town looked very good. I will keep watching.
