My wife and I love the show, it's the highlight of our Sunday nights. I find it interesting, though, how the writers have portrayed the group from season 1 to season 2. Season 1 was more about them being poor and doing what they needed to in order to survive. You feel bad and empathize with them. Season 2 is making them much more aggressive and have absolutely no morals, which seems in stark contrast from season 1. At times they seem like really bad people.
Doesn't seem to matter though, I can't get enough of the show.
