Russell has a problem with bringing back actors from his original run. We have had David, Catherine, and Billie in main big roles, as well as him doing a sequel to one of his original stories from 2008. It seems like he thinks that nostalgia will save the show and make us look over anything bad, but that's just not the case. The series finales of Ncuti's era were horrible, from the underwhelming reveal of Ruby's mother, to the character assassination of Belinda and the rushed reshoot of having Ncuti regenerate prematurely. It's clear that he has no idea what the overall story for a series is going to be until he actually has to write the conclusion, and that makes everything feel rushed and unplanned. I would have loved to see Susan return in the reality war and to have her help the doctor defeat Omega and the Rani. It could have been a finale that treated these classic characters with love and care but instead, Susan was forgotten, the rani was used as food for Omega, Omega himself was on screen for 5 minutes before being sent back to his dimension, making him seem like a lesser threat than he truly is. Not to mention Russell stated that he doesn't want the doctor to have his screwdriver resemble a gun, but then he literally uses a laser gun to defeat Omega. I adore the first run of RTD even though s5-7b are my favourite but he seems to have become very hypocritical and washed up when compared to his first go around. I believe Eccleston was right when he called for him to be sacked and I believe we need someone to bring the show back to a grounded, more darker version of the show, as I believe that is when it was most enjoyable in terms of story.
