catalyst2 | New PA TV series?

According to SCI FI Wire, NBC has given the greenlight to Day One, the pilot for a series dealing with the story of a group of survivors after some unspecified apocalyptic event. It is one of my favourite sub-genres so I'm intetested, even if it does sound like many similar series but then the joy is always in the particular angle that the series takes - pessimistic/optimistic, solitary/cooperative, violent/constructive, etc. - and what it does with that.
