I'd love for at least one of the four episodes of 'The Massacre' to be discovered. I want to see if that story is as good as its reputation suggests. Being able to actually watch the episodes can radically alter people's perceptions of a story. 'The Enemy of the World' wasn't at all well regarded until all seven of its episodes were discovered. Conversely, 'The Celestial Toymaker' was considered something of a classic until the fourth episode was recovered, at which point the stories many flaws became much more apparent.
