I'd say this episode was about average. I liked the Galifrey stuff, but I'm annoyed that NuWho apparently has a "no real companion death" rule, in practice if not written down (and no, Amy and Rory don't count, they died of old age at the end of a good life). Then again, I sure wish I could forget Clara, so I guess something good did happen to the Doctor

I liked how The Doctor just ordered Rassilon and the high council off of Galifrey, although I wonder if they'd be let back once he left.
I'm glad we saw the General regenerate. Ever since Missy appeared, I've heard the stupidest theories from people trying to justify her gender switch while claiming that Time Lords can't switch gender when they regularly regenerate (even though we know The Corsair did). So, finally, we have on screen confirmation that gender swapping during a regeneration is normal, and doesn't need outside interference to happen.
Clara's fate was ridiculous, and I wish she'd actually died (for story reasons, and not just because I dislike her). Still, hopefully we won't see her or Me again. I did like the console room. It was very cool and retro, although I wouldn't say that I liked it better than Capaldi's Console room. The nods and mentions of previous episodes was also really cool (my personal favorite goes to The Doctor's 4 knocks comment).
I actually didn't call Waitress Clara as being real Clara, since I took the rumors that she was actually Oswin as being true. So, that was kind of cool, as was her TARDIS turing into a diner (although that would be a really stupid form for it to keep). Overall, this was an ok episode, although not the strongest and, when it comes to this two parter, I liked
Heaven Sent a lot better. I'm looking forward to the christmas special, and seeing one of my favorite NuWho supporting characters return.
