O-kay. We've agreed that opinions are subjective, so I'm not going to say you're wrong for liking a story I despise, and hope you feel the same. That said, I don't find the sandminer characters in Robots of Death boring at all. Take the information given in the episode, be observant as to body language, facial expressions, speech patterns, extrapolate, and then add some imagination. Plot your story, write it, and there you have a fanfic. I'm not saying these characters are stupendously wonderful - but I do find them interesting. Leela's learning about science is part of her character development. She starts off as an illiterate, superstitious "kill first and ask questions later" savage, and gradually becomes more educated and civilized... up to a point. That must have been some wedding night with Andred!
