Bit of a rant: The fire was a good idea, but the execution was terrible. They were fighting it about as stupidly as they possibly could have. I'm no fire fighter (and I realize that they weren't either), but just throwing pots of water on the already engulfed house was obviously done. When the tractor pulled up, I was like, "Oh, they're going to dig a ditch to keep the fire from spreading, that's actually smart." No, wait, they're just going to knock down the house (whose roof is on fire) and ignore the fire on the fence. Gah. I realize in the grand scheme of things it doesn't matter, but it annoyed me greatly. /rant
Other things:
I like the kids wandering around the edge of the dome, mapping it out. Normally I find kids to be detestable in these shows.
Nice Truman Show reference with the dog's name.
Angie should get out of the emergency shelter ASAP. Or die. Either is fine with me.
The ending with the cop shooting was kind of dumb and seemed forced; I think they could have handled that better.
