I liked the somewhat sombre and laid-back tone of this opener, though it could have done with being ten or fifteen minutes shorter. It looked expensive, and kudos to the director and crew for keeping it convincing. There was much to like about it. We may be done with motormouth Doctors for a while, but this new incarnation of the show seems to have its own style of wit. Loved the scene with the homeless man; humour, intrigue and menace all in one scene, and very well-shot too. Capaldi doesn't even try to compete with Matt Smith, but that's not to say that he won't own the role just as Smith did. Looking forward to more of this new, perhaps edgier, flavour. Will need to experience the title sequence and theme tune again before deciding, but on first impression I find them both to be superior to the ones with which the Smith era was originally lumbered. They evoke a sense of weirdness and mystery, which seems appropriate for the show's new direction. Kind of got a sense of Pertwee's later title sequence from the graphics, too. Anyway, four out of five. A very robust opener despite some misgivings.
