Meh. I was not roused.
It was just an ok episode. I think Capaldi will be fine, but I wish he were just a straight up old fashions doctor. He seemed a bit too manic in this episode.
And I agree with the forcing of Clara's emotions towards the Doctor. It was almost as if the writers had sat in front of the camera and said, "Look guys, the Doctor is not old again. Get used to it. He's not going to be the young, fun, crazy guy you're used to. He will still be cool, but just give him a chance, mkay?"
I'm ok with him being old and cranky. Other Doctors have been. They've gotten by with their smarts and resourcefulness.
I'm not sure the Doctor advocating the robot's suicide is much different than outright murder. The Doctor usually reserves death for extreme cases, preferring to recommend a change in ways. Not sure about the final scene with Paradise. I wonder if it comes up again later, or just a strange closure scene for that episode.
