I finally got a chance to watch the two part season finale today and (unlike a lot of people it seems) I really liked them. Some excitement, some fansquee, even some emotion.
I'm not sure about everyone else, but I was quite surprised by the revelation that Missy was The Master. The whole giving control of the Cybermen to the Doctor was I thought a cool idea in light of the Doctor's ongoing moral dilemma this season.
I never particularly cared for either Clara or her relationship with Danny Pink, but I still got a bit caught up in the emotions of him being a Cyberman, saving her, and in the end not coming back in favor of the boy he accidentally killed in the war.
The irony of both the Doctor and Clara, giving up their relationship under the false impression that they were doing the other a favor so their friend could be happy was probably the first time I actually felt anything for Clara beside mild annoyance. ;)
Now, I'll just have to wait for more... :'(
