The Spectre of Lanyon Moor is a good story, with some superb acting, that sadly is a little too long. Unlike other stories that feel long, it's not because there are superfluous, 'nothing' scenes. It seems to be a little 'fat'. You could rearrange some scenes, and combine others, and it would feel a bit snappier. At over 2 hours, it could probably use with 20 minutes being cut out.

The plot is an interesting piece, with little twists and turns, that has a comforting feeling like a walk across a damp moor in October. The setting was a pleasant one, all the more because of the return of Brigadier Lethbridge-Stewart, played by Nicholas Courtney. The Brig fits well within this story. He adds another familiar presence that carries a nice chunk of the story. The continued banter between The Doctor and Evelyn really feels like a couple of good friends teasing each other.

There are some good guest actors in this one, mainly the married couple of Susan Jameson and James Bolam, who add a nice energy in their performances.

While I have issues with this one, there is still enough in here to enjoy.
