i thoroughly enjoy the first part of this two parter and the impossible planet and and be slightly worry that the second part wouldn not hold up quite so well a have be true in the past of the two parters of the past 2 who series . but thankfully my fear be unfounded a i find myself enjoy this episode as much a the previous one . anyway we start off with the survive crew member on the run from the ood and whom have become the devil pawn . there be also a bit of philosophize on the doctor part in the episode that i quite enjoy . needless to say it be a good solid doctor who story . might be a tad too intense for the young viewer though . my grade represent b plus .
