I'm just going to say it: this episode did something very, very smart. Now before you all write me off as delusional and/or unintelligent, please observe that I am actually not speaking of the aliens this time. Many reviewers have complained about the fact that with NuWho too many episodes take place on Planet Earth saying that Classic Who would never commit such an atrocity and that this aspect of the reboot has completely ruined the series. I respectfully beg to differ. While I may not have grown up with Classic Who, I have watched as many of the old series' as I could find so I am up on 'the old ways'. And yes NuWho is very different in some aspects to what came before. But that's just the point: times have changed, audiences have changed, the world has changed. Heck, The Doctor himself changes pretty regularly as does the TARDIS interior and the companion so I don't really get all of the complaints. Well, I do but I don't (if you'll remember, I wasn't favorably impressed by the burping garbage can in Rose but I loved the bits with 'internet nutter' . If you're not a fan of the way the series has changed, just don't torture yourself by watching it.
This episode had great potential and as I was watching the first few minutes, it looked as though all of my expectations would be fulfilled. Perhaps this is why I take such umbrage with its descent into crass and un-funny humour and the mish-mash storytelling. Christopher Eccleston was amazing as always and, with the exception of the Slitheen and Mickey, the rest of the cast were wonderful as well. It's hard to truly pass final judgement on this episode just yet, as it is a two-parter, so I will reservedly give it a 7/10 simply for the opening 11 minutes.
