Credits: Watching them again, they seem much cleaner, brighter - a credits sequence for the video tape era. It was the source of an interesting, but friendly, disagreement between Jacqueline Hill (initial companion Barbara Wright, and Lexa in the following serial Meglos) and First Doctor William Hartnell - he wanted the series modernised, shot in colour and made much more visually impressive while she felt the series was much better suited to dark angles and mystery. I can completely accept both points of view - with the romantic in me probably siding with Miss Wright.
Post-reprise: I'm going to go on about, I can tell, but the music really is very intrusive as Pangol goes to the control panel.
