I may not feel as strong if/when I rewatch it, but it was so refreshing right now to see him *have* a deep emotional reaction to something. It was mostly Ten in DiM/EotD with a bit of Nine in Dalek thrown in so he would actually beat the thing, but it still seemed like "my Doctor" poking through when facing his arch enemy. The ones who always survives when he loses everything.

The rainbow Daleks are so very lol worthy.
