I liked what I saw even though there was nothing new, so to speak. I also wish they didn't spell out that "ATLANTA IS BAD!!!!" before he went there. Granted, considering how he arrived there in the pilot I already knew what was going to happen -- either they'd be overrun by zombies or we'd get the 28 Days Later type of human compound -- but still, you don't have to spell everything out in advance.
The father and son were the best emotional beats of the pilot, with the cop putting down half-zombie lady in second.
