I know ep4 didn’t really ring my bell as much as I hoped. The second part of the story more than made up for it.
The Slitheen seem determined to turn the world into a radioactive mess by faking an alien invasion and then auctioning off chunks of the Earth to fuel interstellar drives.
And the Doctor has to ruin this. What a spoiler.
Effects: An improvement on the previous week. The costume slitheen is still much better than the cgi Slitheen.
Acting: All good, but I feel I must comment on Penelope Wilton who really outperformed everyone at the end. As did the lass who plays Rose’s mum, although offhand I can’t remember her name.
Sets/Locations: The destruction of Downing St (and most of Whitehall by the looks of it) was spectacular.
Script: Back to form.
Overall: Back to form. (Is there an echo here?)
