Leaving aside my pro-Mccoy bias, this serial is incredibly good. This was the last classic Dr who to be recorded and it shows in many ways. Mccoy and Aldred are in brilliant form, complementing each other wonderfully both as partners and when they argue over being in Gabriel Chase. The supporting cast is also brilliant, with no weak links at all. Particular mention must go to Sylvia Syms, with a performance that manages both creepy roboticism and (in part 3) wonderful human regret, and Ian Hogg, who manages a great balance between cold scheming and internal torture. Leaving aside the performances, the production values are superb. The 19th century victorian feel is evident, and, in tandem, with Alan Wareing's direction, gives the story sense of underlying menace. The best part about Ghost Light, however, has to be the script. To quote another reviewer: it is "Good Weird, Brilliant Weird". Some critics have commented that the plot is nonsensical/silly/too many holes etc, and to this I shall say only two things. First, the story makes perfect sense IF you pay close attention to what is going on. It is a story where missing one or two lines of dialogue might make you confused (not helped by the original audio), not a story that is confusing because of bad writing. Second, as with a lot of Mccoy stories, the structure is as much created by overall theme as it is trad narrative. In other words, the plot is not as linear as something like Remembrance because it is about a central theme as opposed to a story (Full Circle is similar in that the planet environment takes precedence over the story's "plot"). Aside from the story itself, the extras are also pretty good. The making of documentary is very good, as is the question segment with Marc Platt (author). The most valuable extra has to be the audio options- the new sound option gives a score which complements the story, as opposed to drowns the dialogue. Altogether a very good DVD release of one of the very best Dr Who stories. Fully recommended
