I got through season 3 of Torchwood before my heart was too broken to finish the series. I want to watch original Who, and I still have yet to see the Sarah Jane Adventures, but I felt like I needed to rewatch Who ago. So, I started last night and plan to rewatch at least 9 & 10's run.
I've gotten through the first two discs of 9 already, and this time I'm a) noticing SO much more, and b) picking out my favorite episodes/moments.
That being said, I'm pretty sure the episode "Dalek" is going to remain in my top favorites.
This episode made me cry so much harder this time than last time. It's a fantastic character piece for the Doctor; his entire interaction with the Dalek is just heartbreaking and amazing
Especially this part:
http://youtu.be/Hmv80q5fAWU?t=2m49s The Doctor's face after the Dalek says "you would be a good Dalek" is just heartbreaking. I've gotten so used to the teddy bears of 10 and 11 that I really forget just how angry and raw 9 was. I wish I could find a video clip of the Doctor and the Dalek in the cell. Oh god, the feels. Talking about the war and how both races are now gone.
Then there's the fact that this episode makes you feel just so heartbroken over a dalek.
