If must watch tv shows were food we would all be anorexic right now, so I looked up lists of most watched/best/greatest tv shows of all time.

Some interesting results...
Game of Thrones is consistent in the top 10 as are The Sopranos and The Wire.
Fargo, Deadwood, X-Files are regular listings while Breaking Bad seems on average the highest rated.
Unless I missed it Westworld doesn't feature ?
The Leftovers ? Any good ?
In short, apart from GOT most of the highest rated have ended, many ended a good many years ago.
Is there anything coming to top the front-runners or are we in a period of mediocrity?
