Terry Nation's estate own the rights to the Daleks, and I think they were holding out for a better deal, obviously forgetting that they were previously happy to license the image to Victor Lewis Smith for his Gay Daleks sketches in TV Offal.
I watched the first one and enjoyed it, and I'm looking forward to more. The first one was a bit of a catch up episode for those perhaps unfamiliar with the whole mythos, and it was pretty well done. Some cheesy bits, but it wouldn't be the same without them.
