If you have Netflix, you could give Glitch a try. It's an Australian supernatural/fantasy show with apocalyptic themes, particularly in the 3rd (final) series. Might not be everybody's cup of tea, but I quite enjoyed it.
If you fancy something a bit different and don't mind subtitles, me and my missus have just binge watched the Are Murders.

Quite a lot more grisly than your typical UK/US equivalent. Again, you have to not mind subs though!
