Guess I'll settle for Walking Dead and Game of Thrones now.
You might try “The Wire” - I thought it had exceptionally interesting characters and lots of great dialogue. It can get a bit tricky to follow - there are usually a number of plot lines developing simultaneously, and sometimes it’s hard to keep track of the large number of players (especially in the drug gangs) who populate the series. It’s probably not for everyone, but if you stick with it, you’ll end up wondering why our big cities aren’t even more screwed up than they already are.
