My wife and I currently ran out of our favorite shows to watch (last one was Alias by J.J. Abrams, great show), so we started to watch all the old classic James Bond movies, in order nonetheless.
These are the shows we've been watching the last couple of years:
Midsomer Murders
Death in Paradise
Foyle's War
George Gently
Alias
Arrow
Flash
Gotham
... and I've forgotten what other ones. We've liked all of the above and will continue to watch them when new seasons come out.
Besides the drama shows, we've been watching Biggest Loser, Chopped, Cutthroat Kitchen, Kitchen Impossible, and Worst Cooks on a regular basis.

And not to forget, I've been watching Expanse now this season. Great show as well.
