Okay, well that was one hell of a ride. I've decided to indulge in a bit of self-centeredness and post my 10 favorite episodes, with commentary from now and from when I first watched the episode. These are in chronological order, not in the order in which I liked them. My 5 favorites in order were Dalek, The Silence in the Library 2-parter, Blink, The Empty Child 2-parter and The Unicorn and the Wasp.
1. Dalek - Series 1/ Eccelston+Rose
Then
Now: I've said it before, and now having watched all of the modern Who episodes, I'll say it again. Eccleston is my favorite Doctor. All three of them were excellent, in their own way, but Eccleston is the one actor who brought a measure of danger to the role. The acting when Eccleston showed his anger at the captured Dalek was a great bit of acting. That little bit of emotive resonance (with the help of the fantastic setting of "The End of the World") are what truly made me a fan.
2. The Empty Child/The Doctor Dances Eccleston + Rose + Jack
Then:
Now: Of course these two episodes were going to be on the list, as I imagine they are on most peoples. Fantastic. The only part that I don't like is the repetition of the "Are you my mummy." But, as I later found out, Moffat loves doing the repeating line thing. A small price to pay for quality. These two episodes were the first to really play with the camera angles as a storytelling device.
3. School Reunion - Tennant + Rose + Sarah Jane Smith
Then:
Now: Truthfully, outside of the K-9 bits, I don't recall much of this episode, but clearly I loved the hell out of it when I watched it. Weird how that can happen. Still, the end was emotional for me for some reason. It' very possible I watched this show as a very young child and simply don't remember. At least my repressed memories are of the Doctor...
4. The Impossible Planet/The Satan Pit Tennant + Rose
Then:
Now: Oh, god I should have just skipped the next episode after these. Pavement blowjobs....fuck you Moaning Myrtle. Fuck you forever.
5. Army of Ghosts/Doomsday Tennant + Rose + Rickey's dumb ass
Then:
Now: Poor Donna. First impressions are everything. Fantastic send off for Rose, but one that was ruined a bit when she was brought back.
6. Human Nature/Family of Blood Tennant + Martha
Then:
Now: I doubt this one is among anybody's favorites list, but I really enjoyed it. The WWI scenes stick out for me, personally. It was also interesting to peak inside the mind of the Doctor. Clearly, he wants a permanent companion.
7. Blink Tennant + Sparrow
Then:
Now: Well, clearly, I loved this episode. Thanks again for the avatar, Keyser. Personally, I think they should have kept the Weeping Angels as a one-time enemy. Having them reappear and talk in series 5 really ruined the scariness they showed in this episode. There is a reason everybody loves this episode.
8. The Unicorn and the Wasp Tennant + Donna
Then:
Now: The dialogue turned what could have been a very basic episode and elevated it to something really special. This was my favorite "silly" episode. Very, very fun.
9. The Silence in the Library/The Forest of the Dead Tennant + Donna
Then:
Now: Of all the episodes, these two are the ones that have stuck in my mind the most. The alien life forms were scary as shit, and the Doctor saying "I'm sorry, I'm so sorry" actually made my hair prickle just a bit. Great, great two-parter.
10. The Eleventh Hour Smith + Amy
Then:
Now: Well, this one is sort of pointless, as I just watched this last week. But still, a great introduction to both Amy and Smith. The scenes with little Amelia waiting on him were heartbreaking. Very nice introduction to a very solid season.
Well, thanks for putting up with my questions, comments and dumb observations guys. Watching while talking to other fans really heightened the experience, IMO. Very sad to have to wait for a year plus for new episodes, but I now have 40 years of backlog to work through, so it'll be time well spent.
