I'm loving The Leftovers too - can't wait to see where this goes. I also love Under The Dome. I read the book by Steven King, but it is nothing like the book. The book was great, but they are really building so much more of a story into the series. The show goes by so fast.
I haven't seen Orange Is The New Black yet, but it is on my list! If you like prison shows, you must check out OZ. I have that on DVD and bring it out every few months to re-watch the entire series. You have to be okay with violence and male nudity though
Someone mentioned Charmed - I too love this series, and have that on DVD too. I was so disappointed when that show ended, as I think it could have gone on forever with all the story lines.
