The Doctor Dances - clever plot, great ending
Rose - a good, solid start to the series
Bad Wolf - satirical and Daleks - almost half a million of 'em
The Unquiet Dead - are you Local?
The Parting Of The Ways - good stuff, but the Bad Wolf line faded and came over a bit stretched, I thought
Father's Day - classic time travel paradox story
Boom Town - redeeming the Slitheen
The Long Game - not bad in itself; great prequel for Bad Wolf
World War Three - Harriet Jones, MP for Flydale North!
The Empty Child - Spock!
The End Of The World
Aliens of London
The Doctor Dances down to Father's Day definitely fall in group one for me. From Boom Town down to The Empty Child form another group - not so consistently good, but with redeeming features. I didn't really get on with Dalek, its plot was just trying to be too clever, I feel; The End Of The World had a weak storyline and Aliens Of London was just too comic.
