I'm so sorry" moments). I think he also portrayed better than any other Doctor pure unbridled joy at the sort of thing you'd expect the Doctor to be carried away with.
But the Tenth Doctor died. I'm not one to disparage his farewell tour as some do. I think 10 was probably the most feeling Doctor to date, and why not depict how hard the transition of leaving a version of yourself would be? But as Ten himself would have said, everyone dies, and everything ends.”
I agree about this, especially the joy part. On the other hand when he was portraying the Docor' s own pain, most of the time I felt like the pain he was portraying human and I just didn't feel like he was portraying 900+ years of pain as I do with Matt Smith though. Maybe when he was cradling the Master in his hands in Last of the Time Lords was an exception.
As for his departure, personally I didn't have an issue with portaying how hard it would be for him to leave a version of himself, but I wished for some character development, in which he would accept that "this song is ending, but the story never ends" in the end. But we didn't get that, even after he threw the temper tantrum with Wilf and then seemed to accept his fate we still got "I don't want to go" in the end? I just wish they would have him regenerate after his sene with Rose, which was sort of a poignant scene in itself (even though I dislike rose's character very much).
But the OP doesn't want to bring 10 back, but to have DT back to play a different Doctor. I already explained why I don't think it would work.
