These are mostly deep, heavy titles. What is the other half is not into that, wants a little fun, or at least something that is not "that" dark? There must be something in the lighter genre that can catch and hold a viewer's attention.
On the other hand, in our case, the missus liked to watch Skyrim, and there was a time when she "demanded" me to play in the evening so she could fall asleep easier
She also watched me playing Starcraft II back in the day, so much so that not much later she pushed me out of the chair and played the campaign herself (a couple of times, actually). There were more games to follow, and though she never became a "gamer" (nor am I, actully), she still likes playing and watching games, occassionally (these days, her favourite to watch was the Witcher III)
So, like the article suggests, just give it a go, you never know, and might be actually surprised
