Didn't You Kill My Mother is an excellent story that starts the fourth and final Eleven & Valarie box set. Similar to All of Time and Space from the second set, this tale is an imaginative and different take on a Doctor Who story. It's a quirky and imaginative opening part of what seems to be a four part story. The twists and turns in interesting ways, and really starts to pay off the entire Eleven & Valarie series. The themes it explores are fascinating and a welcome expansion on what has been explored already in this run. The voice cast does a magnificent job, with guest actors Lara Lemon and Homer Todiwala giving amazing performances. If the rest of this box set stays at this level, it should be a perfect ending to an already exceptional series.
