I watched a few episodes of The Rain and while it has impressive CGI, the acting is school-play level. The Killing or Borgen though a bit older are much better IMO. Also, while even older, Lars Von Trier's The Kingdom is fantastic tv.

The lecture hall at my university is featured in that show, the institute of computer science took over institute of anatomy so we have tiles in our lecture hall so it could be washed.

I found the rain a very generic postapocalyptical series. Come to think of it, can't really think of a good postapocalyptical series...
