I am not a Whovian, and let me say their fandom is every bit tantamount to Star Wars/LOTR/Harry Potter, etc.
That episode was weak, Dalek insane asylum? What was that like four rooms of anemic Daleks?
They can't even get through doors? WTHeck they were bred to be super intelligent and get through any technology and they can't get through freakin doors or attack the intruders with impudence. It was like a really pathetic haunted house or something.
The whole syntax was that these were "the most insane out of control hatred=filled Daleks". The other ones were to scared to go down to the planet, what was that, that wasn't scary it was weak.
Ugh, that show always makes me amazed how aloof it can be.
