Let's see, my ratings:
Deep Breath - 7. Not amazing, but pretty good, better than Christmas Invasion for a new Doctor.
Into the Dalek - 5. Good acting, OK plot, awful effects.
Robot of Sherwood - A solid 0. WTF.*
Listen - 10. Some weird crazy slingshot upward from the previous episode.
Time Heist - 9. Not perfect, but a better-than-solid episode.
Caretaker - 4. You know, the acting this season is really top-notch, even from the minor players.**
Kill the Moon - 1. Really great acting. The last shouting match saves this from a zero.
Mummy - 7. OK, see, we could have had stories like this all along, where have the writers been?
Flatline - 7. Well, someone was able to get Capaldi's subtle humor done well in the script.
Forest - 8. The first ending was a bit cheesy, and the second ending was just plain weird, but the episode as a whole was great.
I also haven't yet watched Dark Water, though I'm looking forward to it.
*So I'm looking through an episode list, looking at the writers, and thinking "Why the fuck are they still letting Mark Gatiss write for the show?"
**Speaking of writers, this one was written by the same person who wrote The Lodger and Closing Time. I guess he didn't get the memo that Capaldi's doctor just wasn't going to be quite as humorous as Smith's?
