Season 12 of the cult-classic series “Doctor Who” brought longtime fans all of the aliens and adventures that were missing from the prior season. After the departure of former writer Steven Moffat an almost entirely new cast, the show had some issues finding its stride again in season 11. However, Jodie Whittacker’s performance as the iconic Doctor paired with several cameos by classic whovian villains–such as the Master, Cybermen, and the Daleks–helped get the series back on track. The final episode of season 12 will premiere on March first on BBC and Amazon Video.
