After I watched the 50th anniversary and 2013 christmas specials, I swore to myself that I was never going to watch the show again and I’ve never looked back.
You didn’t like the 50th anniversary special? why?
I’ll try to give the short version.
It came off to me as something that was heavily studio influenced by the BBC to keep the show going on forever for their own selfish agendas by retconning nearly everything Russel T Davies and the classic series established.
I also didn’t like the idea of the War Doctor.
Also, nothing of what you see in the 2013 Christmas special is what Steven Moffat (who ruined the show) had in mind for the eleventh doctor era from the beginning.
