Self-Propelled Barrier of Stupidity
A non-critical minor character whose sole purpose is to make things harder for the Hero(es) to achieve their goal and cause complications along the way. There is no way to educate, negotiate with or otherwise talk sense to a SP Bof S
, and this is apparent to the audience from the moment they appear. This is often the abusive sibling or baby sitter. Can also be an uncaring government bureaucrat
, the Stupid Boss
, or the school principal (when not a key character in the story). A SP Bof S
need not be in a defined position of authority over the protagonist. Unlike The Millstone
, the SP Bof S
is an outside obstacle, rather than a member of the protagonist's adventure troupe who inadvertently screws things up. Also, The Millstone
is usually a more developed and well-rounded figure, with a backstory, etc.
- Harry Potter and the Methods of Rationality: Harry sees almost everyone who tries to prevent him from doing what he thinks is best this way, and occasionally mentally labels people 'PC' and 'NPC', with not a particularly long list for the the former. He becomes even more committed to this view after various unhelpful people blindly following orders leads to him being a matter of seconds too late to prevent Hermione from being killed by a troll.
- The colossally ignorant older brother in Weird Science.
- Dr. Fredrick Chilton in Silence of the Lambs. In many ways, he's the tool's tool - actively confounding the crime-solving efforts of Agent Starling and working toward his own demise at the hands of Dr. Lecter. Although Chilton's death does not arrive by the end of the movie, it's so close we can almost taste it.
- In basically every movie where some scientist main character comes up with evidence that a disaster is imminent, those people who ardently refuse to believe him. Often a Commander Contrarian who is likely to cause his/her own death.
- In Action films, this will be the FBI if the protagonists are local cops, local cops if the protagonists are FBI, or both if the protagonist is independent of either two groups (if either one isn't the Big Bad or working for them, that is).
- Ed Greenwood is fond of using these as guards in his novels. No matter which protagonist (or group thereof) encounters them, unless they're personally known to these stalwarts they will try to run the 'interlopers' off, arrest them, or kill them outright...anything but check whether they might have actual legitimate business that requires them to move past.
- In the 1970s Doctor Who serial "The Silurians", UNIT and the Doctor have to deal with Dr. Lawrence, director of a nuclear power project. The man refuses to accept that there is anything more happening than possible sabotage and equipment problems, even as people die or suffer nervous breakdowns around him.
