8. ‘Dr. Who’
No sci-fi show list is complete without “Dr. Who.” The series started in 1963 and featured several men as the doctor—a time traveling, eccentric alien—and his comrades. Sure, many of the monsters were terribly cheesy, but it is a classic nonetheless. The show was canceled in 1989, made a brief return in a TV movie in 1996 and then was fully resurrected and came back into production in 2003. It continues today.
