This is my favorite of David Firth's triptych film devoted to the medical health system. It has the same ezine sort of graphic style, the same caustic humour, a strong critique of the way the medical system treats patients, and the same crazy narrative and characters. This film is rounder than the previous two, both in the way the story is presented and the message is told, perhaps because it focuses on mental issues and everything seems to be clearer to understand.
There is a lot going on in the film. Some of the skits are really funny, others are really sad, and others are really insane. The main thing is that the embedded message is really serious and important. The Unfixable Thought Machine puts the finger on the wound, on the way the medical system (occasionally or repeatedly) mistreats patients, actively or passively: by ignoring them, by blaming them when the medication doesn't work, by attributing their illness to psychological problems, by prescribing too many pills, by prescribing drugs that doctors are paid to prescribe even though they do more harm than good, doctors who make the patients feel like a nuisance, and so on.
This is not a film easy to watch. You have really to focus on what lies behind the craziness and the caustic dark humour. Yet, it is worth the attention. Take it with a grain of salt, and a good sprinkle of chilly and pepper.
