You know, I am not sure what it is - but my wife and I have NOT liked so many of the shows suggested - and suggested by others.
We didn't like the Sopranos. Or Homicide. Or The Wire. Or anything Yellowstone. Or Ozark.
Some shows, we lasted longer but eventually lost interest. Like The Last Kingdom. Or Dexter. EVENTUALLY we just bored of them.
Grant you, the two of US have different tastes as well. I like Jack Ryan. Wife likes Virgin River and the Gilmore Girls.
I loved everything Walking Dead. We both like Outlander.
On regular TV we like cop shows, courtroom shows (mostly), spy/military type shows and medical shows (mostly).
The "mostly" is because many of these shows are just thinly disguised night-time soaps or silly melodrama. And in one case, just seriously too woke and preachy.
