Doctor Who (1963)TV series

It’s the series that never ends. This beloved BBC classic began in 1963 and is hailed as the most successful sci-fi series of all time (take that, Star Trek). With its rotating cast of leads, including such names as David Tennant and Matt Smith to Jodie Whittaker and soon Ncuti Gatwa, this show spans the ages (and generations). Following the adventures of a time-traveling extraterrestrial being (the Doctor), the series follows the ever-changing hero as they fight to save various civilizations using the iconic TARDIS (time-traveling police box, obvi) to hop from one point in time to the next.
