Tough choice.. I might finish the final season of Downton Abbey, which I missed due to my work schedule!
Everyone is screaming at me to watch Westworld!
I just finished season three of Downton Abbey because I was home with bronchitis. BTW watching that tear inducing season did not help my congestion. Anyway, I'm soldiering on to season 4.
I would watch the British Bake Off show all my local friends were obsessed with.
I'm updating my answer.. Stranger Things season 2!
