3. Dr. Who (1963-Present)
"It won't be quiet, it won't be safe, and it won't be calm. But I'll tell you what it will be: the trip of a lifetime."
We're going to take a guess that almost everyone has seen at least one episode of Dr. Who. And if you haven't, well, get on it, because you have 798 episodes to choose from -- got to start somewhere! Since its initial premiere in 1963, the time-traveling humanoid alien known as "the Doctor" has been cast 12 times, churned out 34 seasons, and garnered respect from audiences for which it is difficult to classify as a "cult" following anymore, what with the massive, continuously growing fan base. Celebrate your inner nerd. Watch Dr. Who!
