5. 'Doctor Who' (2005 - Present)
Having started in the '60s, but having found nearly mainstream status in recent years, "Doctor Who
" has television's most perfect concept when it comes to producing an endless engine of stories. It centers on a time traveller who can go anywhere, any when
, and when he dies (or the actor wants to move on) he can "Regenerate" into a new face and start the timey, wimey journey all over again. Yes, some of the production values border on laughably cheap. But the show's passionate, poetic, and emotionally "I can't even" storytelling are some of the richest that the genre has ever seen.
