I never read the comic nor ever heard about it prior to stumbling on it via Netflix suggestion. My wife and I were instantly addicted to it and watched Season 1 in two days. I have never been a fan of Time Travel themed stories, but they did a fantastic version of this theme with some truly great characters that apparently each have some really compelling back stories. With all these Time Traveling story lines, you definitely have to pay attention because the writers do throw some curve balls at you, but overall I loved Season 1 and look forward to Season 2.
