Right-o, in no particular order, my ten favourite stories from the new series - first five in one post, second five a bit later.
Father's day, First series with Eccles and Bille. The whole thing hinged on the story, and it wasn't straight-forward 'Doctor waves the sonic and all is well'. Showed the sweetness of the relationship between the Doctor and Rose, from the big majestic acts of sacrifice to the little touches in the dialogue (In response to Rose teasing him about being like Father Christmas 'Who says I not? Red Bicycle when you were twelve.. etc' this is not exact word for word, mind, rough gist)
The Empty Child/The Doctor Dances, First series with Eccles and Billie. It's still one of my favourites because the eerie works so well, and the Doctor is just so very Doctorish, and there's running in corridors, and jaw-dropping innuendo. I think Moffat's characterization of Rose is also much better here than in Girl in the Fireplace.
Parting of the Ways, first series finale. Daleks actually being scary, real devastation that isn't reset, RTD having the balls to kill a very likeable possible companion (Lynda) and in a really quite disturbing death, too, and the perfect ending for the battle-scarred Ninth Doctor.
The Christmas Invasion, with Ten and Rose. Best by far of all the Christmas specials, and one of the best Doctor-lite stories (probably because it wasn't officially Doctor-lite, but anyway). It's funny, it's a bit epic, Harriet Jones is a great character, and the Doctor opening the TARDIS in his pyjamas with 'Did you miss me?' is one of the very best Who moments, ever.
Fear Her. Nah, just kidding.
The Impossible Planet/The Satan Pit. Ten and Rose. Primarily because it scared the crap out of me, but also because it took the Doctor way out of his comfort zone, with the actual Devil in front of him, but also because of having to perhaps think about settling down with Rose. Big and little, which is always good. The supporting cast are brilliant, and the TARDIS rescues the Doctor. All good.
