I liked it less than the previous part. Doctor Who has a whole bunch of less serious episodes like this one and it is executed more or less correctly, playing between the immediate threat of a nuclear attack and the incompetence of the Slitheens, it makes for a decent comedy with even more political commentary than the previous part.

I think that the FX are a bit uglier than in the previous episode. The transition Slitheen in a costume and Slitheen running in 3D is a bit too jarring but I think they just did what they could and running around in those costumes must not have been easy.

I still don't like Mickey. They just made him a nerd who is now capable of hacking and it's pretty bad. He's still a comedic relief but this time the main source of comedy is either him getting bullied by the Doctor or his incompetence and it doesn't works at all.

The episode is even more on the nose regarding it's political commentary. It has a strong message about war only serving financial interests, all the comedy about the government incompetence and the fact that it's that easy to get access to the nuclear bomb by creating false threats and that it is that easy to launch a missile works great and is surprisingly still never corny.

I really liked all the scenes that are more character centric as it helps developing a lot more the characters and giving hints on their personality, such as when they are sheltered waiting for Downing Street to be bombed, it's great seeing The Doctor not wanting to cause any more casualties than he already has, Rose blase attitude regarding her death, Jackie's concerns regarding her own daughter and Mickey willing to risk it all are just hints of character traits we'll see more of in the future. But I think the character that takes all the spotlight is Hariet Jones. She is just magnificient here, taking decisions as the only democratically elected person in the room. It's just really fun to see all her genius moments and her facial expressions are just really fun.

The ending is a bit too rushed, The Slitheen all being in the same room, naked without their costumes feels a bit too easy and forced and it was a bit too disapointing.

The tone of the episode changes for the ending, Rose assuring her mother she will be back within 10 seconds and Jackie counting to 10 knowing well she won't is a great moment and ends the episode on a more somber and melancholic tone, putting a focus on the feeling of being abandoned.

I think overall it's a less interesting episode than the previous part. It was a good standard Doctor Who adventure, the focus put on the characters is all great but I'm a bit disapointed all the highlights are put in the last part of the episode.
