It's okay but there are so many mistakes in the storyline, so much stuff that does not make sense at all that it sometimes hurts to watch. The cinematography is on a really high level - indeed. However, the inconsequence this storyline was written with is disturbing and makes this whole thing a bit of a painful experience. I quite skipped trough it to at least get an overview where this is going.
Maybe they should have done a deep dive how cultures would really develop under these given circumstances. I find it hard to believe that all those people do not know absolutely anything just because there was a virus. And given the fact, that there is no further explanation I bet Apple itself does not have an explanation how this scenario makes any sense.
The only reason I can see why people would give this series a good rating is because of the cinematography, the cast and because it was done by Apple. Because besides those superficial reasons, there is nothing really that justifies a good rating.
