Oh Dear, how can people call this the best episode in any way, it's not the best Steven Moffat episode, it's not the best Dalek episode, it's not even the best season opener, this is an abysmal attempt at creating a tense, action packed story that falls on it's face in the first 10-seconds, when the Doctor visits Skaro, the daleks' home planet, you know, the one he destroyed in Remembrance of the Daleks, whoops, but the biggest problem here is the Daleks, if you were to take them out of this story and replace them with any other powerful enemy, like the Cybermen for example, then you would have the exact same story. But no, the big thing about the daleks in this story is that every dalek in the BBC storerooms is being put into this episode, apparently, I barely saw any old series daleks at all, and just mentioning that a new series dalek once fought the Doctor on Spiridon, or Exxilon, is not satisfying, I wanted to see some old series designs, not to mention the story makes absolutely no scene. The Daleks tell the Doctor to go into the Asylum to switch off the forcefield, because it can apparently only be turned off from the inside, yeah let me think about that for a sec, not to mention that the President of the Daleks claims that Daleks must not destroy each other as they find that offensive, rubbish, just look at Destiny of the Daleks, Resurrection of the Daleks, Revelation of the Daleks, Remembrance of the Daleks, Evolution of the Daleks, Victory of the Daleks, and while this also shows the amount of imagination that goes into the titles of Daleks stories, if you watch any of these episodes, you'll see that this line is absolute Pony. But still the direction is very atmospheric, the acting is superb, the music is tense and the whole episode runs very smoothly, just a shame about Moffat's terrible script! Not the worst Moffat story, it's certainly better than Let's Kill Hitler, but still one of the worst!
