Defending the Museum is a 2|entertain DVD documentary looking at the Doctor Who serial, The Space Museum. The documentary consisted of Robert Shearman explaining how he thought this story was overlooked unfairly.
Shearman's defence is based on the suggestion that the plot was a parody of other science fiction tales. He evidenced this with example of plot devices. For example, he pointed out that the First Doctor made a big deal of a small thing, but this had nothing to do with the plot as it normally would have.
