I thought it was the weakest start since Ecclestone...
Capaldi didn't have the comic timing - there were obviously a few punchlines in the script, but they were completely off beat. It was really weird seeing someone play the Doctor without any eccentricities, he really was Capaldi running about reciting the lines like he was reading a shopping list. Once he got into the angry thing he was alright, but that first scene and the first scene in the restaurant in particular were soooooooo wooden, especially compared to how Tennant and Smith dealt with similar lines. A big change in character would be good, but maybe the scriptwriters need some time to work to Capaldi's strengths? Because comic timing isn't one of them.
(And yes, I know The Thick of It was a comedy show, but looking back, his shouting character allowed him to be pretty slack with timing. It was the characters reacting to him who needed the timing.)
