This is tough. I love all of them, but Bad Wolf / Parting of the Ways has a special place in my heart. I have so much nostalgia around it and I never get tired of watching it (I guess the same can be said for the other stories) and I never get bored (looking at you, Daleks in Manhattan / Evolution of the Daleks). And it's my 3rd favourite DW story ever and my favourite finale ever, so yeah...

1. Bad Wolf / Parting of the Ways

2. The Stolen Earth / Journey's End

3. Dalek

4. Army of Ghosts / Doomsday

5. Daleks in Manhattan / Evolution of the Daleks

Daleks in Manhattan/Evolution of the Daleks was really bad. Ima say it. But The Stolen Earth/Journey's End is like, my favorite Tenth Doctor story. I'm going with that.
