Quote:The first one that you mentioned seemed to be angry all time, while other one seemed to be like in "grumpy Grandpa" mode!
Yes. He was the one fresh out of the Time War. Newly regenerated. Angry at the Daleks, and angry at himself for his (Erroneous) belief that he'd killed his own race. The idea was that he'd start off bitter and angry at the universe, but that Rose would help bring him round and get him back on track. It was an idea meant to develop over several series, but got cut short due to Ecclestone's premature departure.
When Tennant took over, they couldn't make his Doctor exactly like the previous one. There has to be a contrast for it to work. So Tennant's Doctor is more accessible right off the bat. But... you still see a lot of that anger there. "I'm so old now. I used to have so much mercy. You get one warning. This is it". And it manifests in some very un-Doctor-like behaviour, such as his arbitrary torture and murder of the Family of Blood.
Capaldi was poorly written right from the get go. First off, there's nothing wrong with a 'grumpy old man' Doctor. If you write it well, and give the character the support it needs, it works well. Hartnell, Pertwee and arguably both Bakers played it perfectly. But then, they were helped by good scripts and a clear idea of what the Doctor needs to be.
Moffat never seemed to grasp what to do with Capaldi's Doctor. Sometimes he was emotionally distant, sometimes he showed intense emotion. Sometimes he was written as an older man, sometimes as a younger man. Moffat never gave us a clear line through to who this Doctor was.
And he never gave us a clear line to the stories either. The plots were either paper thin or overly dense. Often they'd start well, but fell apart in the third act.
Capaldi did his best, but was hampered at every turn by the quality of the scripts.
