DRAMA Bill Potts, the Doctor will see you now, it feels like an aeon since we've been able to enjoy the whole "new companion" shtick: What's a Tardis? Are you an alien? This time not "Doctor who?" but "Doctor what?" and, crucially for all novice adventurers with loosened bowels, is there a toilet in the Tardis?

Cunningly titled The Pilot, Steven Moffat's series-ten opener is geared up as a fresh start, a jumping-on point for Bill and new viewers, requiring little or no foreknowledge of Who lore. Pearl Mackie is quirky and instantly winning as campus canteen worker Bill, whose thirst for knowledge means she steals into the Doctor's lectures. For his final series, Peter Capaldi's majestic Time Lord has taken rooms at St Paul's University, Bristol, with his police box resting invitingly in the corner of his study.

Snappily directed by Lawrence Gough The Pilot has eerie moments, a menacing puddle, love in the midst of a war zone, comic asides from Matt Lucas as the Doctor's dippy batman, Nardole - and blasts of Beethoven an Joy Division on the soundtrack.
