Replying to TV shows you got into late

So, I notice that this section of NS is far FAR less active than I remember about 4 years ago or so when I was posting more often... in an attempt now to keep it from dying I thought of starting this.

What shows that were ultra popular when they were having their TV runs did you get into super late or after they had finished their TV runs? For me:

https://www.newschoolers.com/videos/watch/885757/Game-of-Thrones---Warriors^^^^Didn't start this until 3 season had already aired



https://www.newschoolers.com/videos/watch/885758/Sons-of-Anarchy----A-Wonderful-Life^^^^ Only just started watching this last year



Others that stick our are Deadwood, The Wire, and Justified I didn't watch until I got Amazon Prime last year.
