The fourth and final season for David Tenant. This season draws from the old Doctor Who villan achive as well as creating interesting new ones for the Doctor to deal with. I'm not a fan of his travelling companion this season as she always seems to be whining and shouting, but the other characters are wonderfully created, including the reappearance of Rose.
The story lines make you think, they are creative and very different from the regular dregs that TV writers draw upon for most modern TV shows. The final episode brings a natural conclusion to the series. I am curious to see what a new doctor and companion get into in Season Five with new creative people behind the scenes.
For the Doctor Who fan, this is a must have purchase.
