New Earth - an excellent start to the tenure of Mr Tennant! OK so he started in The Christmas Invasion but that was the "save the earth whilst I'm having a regeneration crisis" opener designed to introduce the audience to the idea of regeneration. New Earth was the first true episode for the Tenth Doctor and it bodes well for the new series.
Congratulations as always to the team over in sunny Wales for their continued vision, determination and imagination in bringing this new version of Doctor Who to life.
