Youtube user Brian Rimmer has created this terrific montage of every Doctor Who opening sequence from every season EVAR! I used to watch Doctor Who all the time as a kid, and even now, years later, it still gives me a little thrill to hear the opening theme music. This has to be one of the most iconic TV show intros of all time!
