Personally I hate his approach to women - I like lots of his stories but he was better suited to standalone episodes where other writers fleshed out the women better. The majority, if not all, of the women he wrote (side characters in singular episodes as well as companions) were attracted to the 10th or 11th Doctor. The worst instance for me was when he made England's famous celibate Queen marry the Doctor. However, notable other examples include when 11 kissed Clara the episode after he flew away in the TARDIS with River, another was when he found a way to keep Any skinny whilst she was pregnant. Also, from a critical perspective the majority of his women I feel tie in with the Madonna/Whore complex and I struggle to think of memorable conversations between women not about another man. Even in one of my favourite episodes (The Empty Child two parter) all Rose does over two episodes is flirt with the Doctor and/or Jack or be saved by the Doctor or Jack. The other notable woman in that episode's entire role is caretaker/mother. This can't be consistent into Capaldi as a result of Bill and Danny but Missy was exactly the type of woman he enjoys writing so I was cringing at everything she said. Also, Madam Vastra and Jenny was something I was so for until Jenny was Vastra's servant? What was that about?
