this be an excellent 2 part episode and although i have never be see the old one and i never think the doctor would go up against anything that be paranormal and extra terrestial of course but not paranormal . this episode bring the thing that we most fear and how would we human and in a futuristic time and would fight and defeat real live evil when most odds say that would be impossible . be that it a family film i be surprise that they bring some stuff in like fear and faith and especially if it also go to entertain american audience . but who care about what yank say and we rock . doctor who have show potential ever since from episode one from the new series in 2005 and first be so harmless to scary and from fun to serious and from light to darkness . i hope many old fan will one day soon say the old doctor who have return . positive .
