I just had a conversation with my wife and father-in-law on this very subject. I think that the problem that we (my family) is having with respect to Moffat's Doctor is that he switched the characters of the companion and the Doctor from Tennant/Davies' tenure. During Tennant, the Doctor was outspoken and bouncy, energetic and fun and the companion was the 'straight girl' getting to experience this huge universe that the Doctor lives in. In Moffat's Doctor, the Doctor is quiet and brooding (with a few notable moments of hilarity) and Amy Pond is the one who's outspoken and hilarious (most of the time). This has led many of us to see Amy as outshining the Doctor (because she's more the kind of character we enjoy watching) and now we'll see the show as having lost something important when Amy leaves.
Hopefully, the Doctor becomes more vibrant once Amy leaves or they find a new companion with the same verve as Amy. Otherwise the show will seem lackluster.
Not quite sure I can agree with Tennant's Doctor being "outspoken and bouncy" and not as "quiet and brooding" as Smith's Doctor...well, maybe not as quiet, perhaps, but brooding?
Tennant's Doctor starts out his life by killing the leader of an invading alien race, saying "No second chances...that's the kind of man I am.", and later causing the removal of Harriet Jones from the position of Prime Minister after she orders Torchwood to destroy the Sycorax ship. Rose brings out he best in him, and then, after he looses Rose to an alternate reality, he nearly sacrifices himself to take out the Racnoss, only relenting when Donna pulls him back from the edge of suicide.
Later, he refuses to see what is in front of him with Martha, until he drives her away.
Afterwards, he deplores the fact that he can't change a fixed point in time, and actually has to cause the eruption of Vesuvius, taking out Pompeii, until Donna does it with him, and refuses to save anyone in Pompeii until Donna persuades him to save the one family. Later, after he has to wipe Donna's mind to save her, he ultimately tries to break the laws of time (specifically, the concept of the fixed point in time), thinking he is above them, only to be shown that he is not...and then broods over his coming death with Wilfred, only to rage when it comes time to sacrifice himself to save him...
No, Tennant's Doctor did A LOT of brooding over how he had lived too long, especially after Rose was gone from his life...
