Well I was blown away by the DoD. In the main I thourghly enjoyed the plots and sub plots. However I did find they zygon subplot a bit unsatisfactorily resolved its main point seemed to be to ultimately enable tenant and smith to make their little speech about not allowing another person to make the same mistake their previous self made. The other plot point I was disappointed in was there was no explanation as to how Clara and the doctor got out of his time stream. And given the trailer which I’m not discussing here there needs to be some explanation as to how they got out. By the way I’m for calling the hurt incarnation number 9 as we clearly heard the future cappaldi doctor call himself the thirteenth.
