This one has grown on me over time. Another one where the animation has improved it for me. The Doctor and Jamie running around a present-day airport was a fun setting. Good villains. The liverpudlian, Sarah, who would later play Queen Victoria in NewWho, had some great scenes and would have made a good companion. The absences of Ben and Polly for the majority of the story, which is to be their last, is a shame, but at least they get a goodbye scene.
