Doctor Who finale preview, Death in Heaven Despite the odd disappointing episode (Robot of Sherwood), Peter Capaldi's series has been a great one. It was a wise decision to cast someone very different to bouncy, excitable Matt Smith and has changed both his relationship with Clara (Jenna Coleman) and the tone of the whole series. This eighth run has been significantly darker and creepier - so creepy, in fact, that the BBC has been receiving complaints about last week's episode, Dark Water, being too scary. It's like being back in the Sixties, with the nation's children once again watching from behind the sofa. Last week's episode left a lot of open questions. Unusually for Doctor Who, we even saw a major character die - though whether he will stay dead remains to be seen. For this episode, at least, Danny Pink's (Samuel Anderson) story is not over as he anguishes over his fate in the Nethersphere. Best of all is Michelle Gomez's gleefully bonkers performance as Missy, the regenerated Master, now free from once-doomed Gallifrey and attempting to take over the world with an army of Cybermen. We can only hope that we haven't seen the last of her. Be prepared for a tear-jerking finale, now traditional for a Doctor Who climax. And a thrilling ride along the way.
