One of my favorite things about the Ninth Doctor is his stillness. Christopher Eccleston is so great at expressing emotion with very little movement. Because of that I feel Nine was the epitome of the Oncoming Storm. All that rage and pain simmering under the calm. The times he did rage and break felt true and powerful.
One of the things that I started noticing that he could do, that I don’t think any Doctor before or since has done, is he doesn’t do anything, quite a lot, and yet he’s still the center of attention. Everybody’s panicking, and people are shouting, and Christopher Eccleston, the ninth Doctor, is just standing there, doing practically nothing, just commenting on what’s going on. And you cannot take your eyes off him. He is absolutely the center of whatever’s going down.
