They really need to give the daleks and cybermen some time off. When 2 or 3 episodes out of a limited run every year are dedicated to them, they really start to lose any appeal they had. Personally, I never found them all that interesting(well, tomb of the cybermen ones were kinda creepy)
The rights to the Daleks are with the Terry Nation estate (the guy who wrote the first story with them), and
apparently (although some people have later denied this) the BBC has to use the Daleks at least once every series or the rights will revert back to them, after which the BBC would have to negotiate for them again (which costs money, obviously).
Also, Moffat at one point admitted that the Daleks were, at this point, more famous of being beaten every year than for being dangerous and were overused, and that he would probably need to give them a rest. This was turned into a stupid series of headlines about how Moffat was supposedly planning to get rid of the Daleks forever, and a whole stupid controversy followed. It was all a bit of nonsense to be honest. But I can imagine that having lead to an extra push to just keep using the Daleks.
I agree with you that both of them are overused at this point though, and Dalek/Cyberman stories are never my favorite because there's actually not a whole lot you can do with them after so many stories. This story seems promising though. We'll have to wait and see how it all plays out next week, but like I said earlier, this is my favorite use of Davros since Genesis so far - they're finally giving him something new and substantial to do with the character (again, this is just based on the first half of the story, so don't kill me if it all falls apart next week).
Also Missy and Clara standing on the hills outside of the Skaro city with a first-generation Dalek approaching them gave me goosebumps. I know it's fanwank, but fuck it, I love it.
Best lines:
- "Three possible locations of Atlantis" (I love references to classic plotholes)
- "Unlimited rice pudding!"
EDIT:
I missed this, is it a classic reference?
When Davros is playing recordings of all those classic Doctors - rice pudding comes from one of the McCoy scenes (you can also see a snippet of the scene on one of those screens). It's one of his more famous moments.
