The Eleventh Hour was a well-paced story with enough simplicity to ensure that the focus was never quite stolen away from the new Doctor finding his (new) feet and the budding relationship with new companion Amy Pond. In a nutshell, nine year old Amelia Pond has been uprooted from Scotland to England ('It's rubbish') to live with her aunt. We don't meet the aunt or Amelia's parents ('I don't have a Mum and Dad') but the young girl doesn't seem to need them. She's self-sufficient, has plenty of common sense and isn't scared of anything ... except the crack in her bedroom wall through which voices can be occasionally heard. She's not phased at all by the sudden crash-landing of a blue police box in her garden containing a man in a tattered David Tennant costume who claims that he doesn't really know who he is yet as he's 'still cooking'. After some hilarity as Amelia attempts to find the food the new Doctor needs to aid his regeneration, they explore the mysterious crack - which turns out to be in space/time rather than the plaster.
Twelve years later, the Doctor returns. The TARDIS, all-but knackered by Tennant's ecplosive regeneration, is as erratic as it used to be in Baker's and Pertwee's day and is busy reconfiguring its internal architecture. The Doctor soon meets up with Amelia - now Amy - Pond who is still iving in the same house and working as a kiss-o-gram. Prisoner Zero, it seems, has also been hiding in the house for the past 12 years by using a 'perception filter' to hide a room from Amy's senses. Once outed, Prisoner Zero (who has formed a psychic bond with the coma patients at a nearby hospital), impersonates several humans while, overhead in the skies, his gaolers search for him threatening to destroy the Earth if he is not handed over. I won't completely spoil the ending but, let's face it, you know the Doctor's going to win and Amy is going to get on board. I will add a few personal comments however. First, the criticisms.
