I went to do a Google search of one of my very favorite films, They Might Be Giants. Since I didn’t want information about the band, I added a space and was about to enter, “Film.” But Google offered me, “Ending.” It was only then that I realized that what most people don’t like about the film is its ending. And that is probably because they don’t understand it. So I thought I would take a moment to explain it.
For those of you who are not familiar with the film, it is about Justin Playfair—a respected judge who goes crazy after his wife dies. He now believes he is Sherlock Holmes. His brother is being blackmailed by some very unsavory guys in a bad car. So the brother is trying to have Justin committed so that he can control Justin’s fortune. As a result, psychiatrist Dr Mildred Watson is sent to observe him. Once Justin finds out that she is “Dr Watson,” the two of them are off with Watson being pulled further and further into Justin’s delusion.
The Film’s Real Question
The ultimate question that the film addresses is whether Justin isn’t Holmes. He certainly acts like Holmes. Regardless, a society that insists upon everyone believing whatever everyone else believes is tyranny. (Not that science and economic policy should be based on such delusions!) At one point, in exasperation, Watson tells Justin, “You’re just like Don Quixote. You think that everything is always something else.” And he responds:
Well, he had a point. Of course he carried it a bit too far. He thought that every windmill was a giant.
That’s insane. But, thinking that they might be, well… All the best minds used to think the world was flat. But what if it isn’t? It might be round. And bread mold might be medicine. If we never looked at things and thought of what might be, why we’d all still be out there in the tall grass with the apes.
With such big ideas, it isn’t surprising that many people watching the film get lost in it. But the ending isn’t primarily about the theme but rather about the plot. And the plot is primarily a love story. For Holmes and Watson to truly find love, one of them must change. There are two possibilities. There is the sterile version where Watson “cures” Justin of his delusion. That’s not interesting in addition to going completely against the themes of the film. So they go the other way where Watson fully accepts Justin’s delusion.
They Might Be Giants’ Ending
There are three points in this transition, and it all takes place in the second half of the film. First is when Watson comes back after abandoning Justin for the evening. When she returns, it is as a doctor, but one committed to engaging with her patient. Second is when Watson and Justin have dinner at her apartment. He is grazed by a bullet (Justin’s brother’s blackmailer has decided to hurry things along by killing Justin). Watson thinks he is dead and for the first time refers to him as “Holmes.” The third is at the very end of the film.
Justin and Watson stand in the park, waiting for Moriarty to arrive on horseback. At first, Watson can’t hear the horse galloping toward them. And she so wants to. But then she hears it. And she sees Moriarty approaching. Their love is finalized. The end:
The film is thematically rich and I’ve only touched on it here. There are any number of currents that run through it. However, the plot is primarily concerned with Watson and her evolution of thought.
 This is incorrect. Don Quixote thought the windmills were giants when he saw them from far away. After getting dashed to the ground by one of the windmill sails, he knows that they are windmills. He assumes that his magician nemesis changed the giants into windmills just to deprive him of the glory of destroying them. Don Quixote uses this kind of logic throughout the books.
