Was thinking of TV shows I can watch over and over and never get tired of, even though I now the plots and outcomes. I usually watch/listen to these (in the background) at work while I am doing work stuff to make the day go by faster. Usually these shows have excellent seasons from start to finish. There are some TV series that seem like a good choice but just hit a speed bump somewhere in the middle (Walking Dead, Lost)
My top six (in no order)
1. Southpark (I know it's not "finished" but 17+ seasons is enough to take up a good chunk of time)
2. Fringe
3. Babylon 5
4. Sopranos
5. Breaking Bad
6. M.A.S.H.
Honorable mentions (that I haven't tried and not sure I could do it)
1. Lost
2. Battlestar Galactica
What are some of your favorite tv series that you could watch multiple times and still enjoy them?
