Okay, I love "Ashes to Ashes." But what's bothering me about it is the cognitive dissonance among amateur and professional TV reviewers alike out there. They first note that "Alex Drake doesn't really believe she's in 1981, and thinks it's all in her head," and they then go on to say something along the lines of "it's completely unbelievable that a female cop would wear off-the-shoulder shirts and miniskirts/talk to her male colleagues that way/drink bad red wine in public/whatever."
Put the two together, guys. The reason why she's not acting like a copper is because she doesn't believe any of this is real. In 2008, she wears sensible clothes and acts like a sensible police detective, but as far as she's concerned 1981 is just a dying fantasy she's having.
