I respectfully disagree with this. I watch for the world building and how the series tries to answer the questions of how far would you go/what would you do to survive and to protect your loved ones.
There isn't nearly enough time spent working on either of those answers for my liking but it's enough to keep me coming back.
The excessive gore, violence, dead animals (RIP Shiva) and cartoon - lather, rinse, repeat - villains are why, IMO, the good gawdess invented fast forward!
