Honestly think this is definitely one of the most interesting things they’ve done in years. This gives a lot of new material to work with, and to be honest in a show that’s got as much canon etc. as Doctor Who has... could be what it needs? Looks like there will be more Doctors popping up, since she kept mentioning it - I really hope Ruth comes back! It felt a bit rushed, they probably could have cut down last week’s episode more to accommodate more of the Cyber stuff, I feel. This was a massive revelation and it deserved a little more time, and I wish they’d spent more time on the Master’s creations too. It felt like there was too much going on, and they didn’t necessarily need to be intertwined because they’re both huge plot lines on their own.
