Homeland is a terrific show that manages to maintain smart storylines for 7 seasons. I generally try to avoid binging shows, but Homeland is a show that becomes addictive in the last 5 episodes with all the twists and turns. I see some people criticizing season 3, but that one is fantastic to me. If anything, season 1 is the weakest because things are just getting started.
Wait until Season 6. It starts slow and feels uninteresting for the first 4 episodes or so, but once the big twist happens, it's the most exciting season. I also love the season in Pakistan, Season 4 I think. Those seasons are the most thrilling.
