I think this was a special at one point but now they’re making it into a series. Seriously I dunno why the thought of what life would be like after human extinction would be entertaining… The series is all hypothesis.
I certainly hope it’s hypothetical since we’re still here. I remember the original mini-series (I think that’s what it was) and I thought it was really interesting. You never think about how long your house would be there or what a city would look like hundreds of years after being abandoned.
