David's entry had humor, it referenced the genre of science fiction (robots), it had a melody that one could recall, it had genuine surprise at key moments (the others only superficially created surprise). Also, David's had multiple levels of ideas going, whereas the others only had one main idea throughout. I'm only comparing to the runner's up. I'm sure out of 11k there were probably over 1k that were great, but why blame spitfire? :D:DCompetitions only give an approximation of a meritocracy. Really it comes down to who you know don't it?
