This is a beautiful series with an obsessive and unique storyline. Doctor who never gets old, but sometimes the episodes and character call for an update according to changing times. Firstly, I think we should more storylines like the episode "Smile" starring Peter Capaldi, or the Rosa Parks episode, which either teach us something about history and science, or relate to a possible despotic future or something close to our reality. The episodes with strange aliens who keep eating up people or screaming Daleks are entertaining once in a while, but may get boring and even silly over time. Secondly, the series should introduce characters that cover all races, and not just white men. Jodie Whittaker as a woman was a good start to this trend, but there should be a wider range of backgrounds to choose actors from. I have seen all the seasons, and remain an indomitable fan to date, but j think the series should definitely include such changes.
