It was awful imo
You spelt awesome wrong! Seriously (apart from the incongruous tank scene & Clara being an all important attachment to Unit), this has been the best Doctor story in too long a while.
I thought Missy coming back would be a bit annoying, dead characters usually get a few episodes off, but she was brilliant!, and the episode was actually about the doctor, with a throwback to Tom Baker (I loved that storyline, Tom Baker agonising over killing the Dalek startup, asking his companions if they had the chance to kill baby Steve Jobs... er, Hitler, would they, could they do it).
- and what's with all the Clara hate? I know she kind'a took over the show last season, and her love story was a bit sickly sweet... oh yea, ok, but I like her, especially in a good storyline (https://en.wikipedia.org/wiki/Journey_to_the_Centre_of_the_TARDIS) for eg.
