BBC's Survivors popped up on my Netflix and I clicked with no idea of what it was: a remake of a 1970s show about surviving a pandemic that wipes out 99% of humanity. Well, I watched both series (12 episodes total) in 24 hours.
It's a gripping mix of serialised and procedural (ie, you follow a strong storyline but each episode has a new problem to solve), with tough moments, strong characters that I loved, hated or both at the same time. This show proves that you don't need zombies or other external threats to pitch human beings against themselves. Also, it depicts a forward looking apocalypse: for most people, it's all about building the future.
