I just started watching a few episodes ago. My brother and sister in law have been watching from the beginning. I call them and ask what is going on but your wife will fill you in. I wish I had started sooner but I have no desire to start from the beginning.
I too just started watching on Amazon Prime. It’s paid for itself in free shipping at Christmas and now with free streaming video. So sick of what is on tv and happy to have access to movies/tv of choice on Prime. Daughter told me to watch the Downton Abbey series and now I’m hooked. Almost through season two.
