I don't care what some fans say. Its nice for a change to have a different character in the Tardis. Who isn't gooey eyed over the doctor.
So Catherine Tate is a breath of fresh air.
Its like the original Doctors assistant.
But as we see in the first episode a plot thread apears in the form of Billie Piper.
Just like each season miss the plot thread and you might stumble in the dark, or just get a big suprise at the end.
These Three Episodes are Brillant from start to finish and both the Doctor and Donna seem to be having a good time. Best episode the Ood.
Look forward to the Agatha Christie Mystery and Sontarans.
Well worth the money if you don't want to wait for the boxset way of in October/November.
