Day 455: Horror of Fang Rock Part 2

In order to spice things up with regards to the plot of the story, a group of new characters has been introduced. They're some quite posh people who crashed their sailing ship onto the rocks near the lighthouse. They bring with them a storyline of their own as well, with one of them trying desperately to get back to London in order to make a fortune on the stock market, causing the ship to crash in the pricess and probably killing most of its crew. What's interesting about this plotline is how pointless it all is. We recognise as viewers that the outcomes of this story will have no bearing on what the Doctor and Leela have engaged themselves with. This reflects on how much importance we give the matter. We care about the safety of the lighthouse, and protecting its occupants from danger. We don't care about the squabbles about money that take place within it, partially because the Doctor and Leela aren't involved with it. This comes across as Terrance Dicks holding a sort of mirror up to society, showing that whilst there may be fighting over money and shares and the like, all of this should be ignored when it comes to the important things such as alien invasions and life or death scenarios, because there are always things that are bigger and better than money.
