Well, yeah. He gets a bit better, but it's not until he regenerates that he gets particularly friendly. Until then he's more like a grumpy old man, haha.
But that tends to be a common theme with the Doctor. He is always something of a grumpy old man. Even at his nicest (*cough* Five *cough*), he can have his moments of "******** you guys."
My favorite example of this is the Third Doctor, who just shines in his dislike for authority figures. It's as if he doesn't really recognize the legitimacy of UNIT's leaders - even the Brigadier, who he has a history with and would eventually consider a friend.
