Gimmicks over story. The last season was painful to wade through, but Clara leaving gave me hope. Now she's back, and... it's... I give up.
It's jumped the shark, or Guitared the Tank.
Maybe it's too much budget, where someone saying "hey, what if we get a tank, and the doc rides in playing a guitar, and... we have a castle set, with... 20? 30? extras? All garbed up? and some pyrotechnics on the tank, it's only a 2 minute scene, missy/clara collecting the Doctor who could have been pondering things by sitting nearby some water, eating jelly babies, lost in thought as Missy/clara walk up behind him, "oh, you 2, well, lets get this started then, again, eh?". Or even a several minute chat between Missy/The Doctor, with more backstory on what Missy is thinking/doing, and that she understands the Doctor's position, she too misses Gallifrey, but perhaps the TimeLords had their chance, after all... 'brief exposition', then arguments about their roles in the universe, how each see things differently, and something that EXPANDS the characters, the story, the plot.
Guitar playing, tank riding nonsense.
Think I'm done for now, someone prod me when Moffat moves on.
