Disappointing mishmosh that takes way too long to present anything resembling a story. The performances are excellent, and I am overjoyed to see Donna. And the Time Lords. But, structure-wise, it is a mess. The first half is really just a lot of running around, and an endless ‘confrontation’ between The Doctor and The Master that completely lacks tension and/or drama. By the final five minutes, as we near a cliffhanger, it starts to show some promise. So, hopefully part two will be better than this… 5/10
