I love this story. I think it is brilliant. The problem is that this story is generally ignored by many people due to the stories which were to come (The Girl in the Fireplace and The Impossible Planet/The Satan Pit) but it is brilliant.
Doctor Who here returns to the style and form of its most prosperous period the Hinchcliffe/Holmes era of the show with its gothic horror vibes permeating the whole story. Action packed from start to end, a brilliant script, an enthralling monster, references to The Horror of Fang Rock (see Toby Hadoke's Who's Round Podcast with RTD to have that explained). A scary monster, clever twists and superb acting. Everyone is on top form this week and I really enjoy the way you just see The Doctor and Rose just having fun, something I think there is an evident lack of in Doctor Who (especially in The Classic Series). This whole story culminates in those dramatic final scenes with the establishment of Torchwood, an organisation which will lead to disastrous ramifications later in the series.
A great story from what could have been the greatest season since the return (if we just remove Love and Monsters, and Fear Her, we would have possibly the best season since the return).
