I strongly, strongly suspect this one had its genesis when someone said, Hey, lets have Spitfires in space! and someone else said, Hey, lets have Power Ranger Daleks! One would have wished cooler heads could have prevailed. This story is just bad on many levels. The Spitfires in space, Bracewell saved by the power of humanity, the previously-mentioned Power Ranger Daleks (Go, go, Dalek Rangers!)theres a bunch of things that, taken on their own, one could suspend disbelief over. But when all of them combine, not so much. Heck, there's even a new Dalek Supreme, which is like a regular Dalek with sour cream and tomatoes. It is worth noting the two bright spots. First is Nicholas Briggs doing a wonderful job channeling the Daleks as they were in The Power of the Daleks, and the second is Ian McNiece tearing it up as Churchhill. Also, thankfully, Mark Gatiss, who wrote this story, has gone on to write many more and better ones.
