First, New Earth reminded me of two Star Wars planets. The first, and most obvious, is of course Coruscant. This is mostly due to the skyscrapers shown on the city views at the end of the episode. The second is Taris which is from Knights Of The Old Republic (although I've never played on it, I've read about Taris on wookieepedia). It's like Taris due to the undercity, which sounds just like Taris' does.
I hope we get to revist it again.
The motorway itself at first seems ominous, but actual it's only the fast lane that's bad. At first I thought that the government of New Earth was being controlled by aliens (like in The Long Game) or had purposely released the crab-things into the motorway.
How did the crab-things (I know they start with an M) get there anyway? It bothers me how it's not explained. If there was a breeding population there before the motorway/undercity was sealed off then surely it would've been dealt with. Also, if the undercity was sealed off, how did it rain at the start? Also, why would the senate still be in session if all it's members were high? hy were the drug people still there if buisness had plummeted? Ah questions, questions.
Anyway, onto the good/cool things:
*Kittens! < 3333 Kittens always make me squee with glee
*Ardal was brilliant and at the start he really did sound like Dougal
*Gah stop mentioning Rose, it's annoying
*Martha's smarter then Rose
*Married elderly lesbians that knit!< 3 And a carspotter < 3
*I loved the references to New Earth, because that's one of the best episodes (I so need to get it)
*The cars are so cool, especially how each is different as a reflection of their owners (I loved the Japanese girls car)
*The intercar communication reminds me of MSN 'You have to be on their friends list'
*The Face Of Boe < 3 Again, another ickle squee, though he dies which is sad:(
*His last words, foreboding much?
*The people of New Earth were so stupid to be killed so fast, but a planet-wide quarantine was a good idea
*Everything on New Earth is preceded by New isn't it? New New York, New New Jersey, New Atlantic...
Next week is the Daleks (they'll never die will they?) and pig-men that look like the larger versons of the one from Aliens Of London. The uber-blonde chick annoys me already, I hope she dies. Panaka's in next week too, most likely he'll die as well.
I've rambled far far too much methinks, (it's odd how this ep has made me rambley, I guess it means I really like it) so I'll go away and return to writing now.
