I know I've been a bit remiss with my series 3 reviews (mainly due to not having the computer at home) but I had to say something about Saturday''s climax to "Utopia" which saw the return of the Master (in two incarnations) and Captain Jack to the series.
In what was otherwise a fairly humdrum episode we had a really clever way of revealing the Doctor's arch enemy via a fobwatch - the same device the Doctor himself used to hide in 1913 - and Derek Jacobi's kindly Professer Yana turned evil just before suffering a fatal gunshot. Raising the stakes and giving us a humdinger of a cliffhanger to what was, in effect, the first of a three-part story, the dying Master steals the Doctor's TARDIS (as well as the severed hand tended by Jack) and makes his escape transforming into John Simm once inside. The Doctor, Martha and Jack are stranded at the end of time at the mercy of the nasty Futurekind!
As if that wasn't enough, next week we also have the now annual celeb-cameo-fest with Ann Widdecombe, Sharon Osborne and McFly all cropping up as themselves in "The Sound of Drums" where the UK has The Master as its new Prime Minister, Mr Saxon.
