this be a clever piece of writing and be full of imagination ( something i always like . ) billie piper and david tennant do another fantastic way of make everything so believable and real . the thing i like most about this episode be the way they finish it . usually the only way to stop a monster be by shoot it and or find a code that will make them have their emotion back and where a this one be just take away the nightmare with a song . this episode also prove what a strong character rise really be and and how far she have come from be just an ordinary young girl to be the doctor side kick . that all i be gon na say on this and but i just want to ask and have anyone else notice that the inside of the tardis look a bit like the outside of a dalek .
