Just saw the pilot. So far...nothing has grab my attention. I feel like I'm watching I Am Legend all over again once we see what Chicago looks like. Figured out who this General Monroe character was from the beginning. As for those pendants that are able to power up electronics, I've been wondering how they work after I saw them in the trailers. Now I know (sorta) or have a theory to how they work. Still want to know 'why' the electricity, or any type of technology is turned off.
As for the characters, other than Charlie's uncle, no one else interested me, not even Charlie. Might take a while or re-watch the episodes a couple of times when they air for me to like her, but from my first impressions....she's boring. Hot, but still boring.
