These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
It's implied that many of the higher ups in the government are also off their meds. Dupont's office is filled with art which is banned and his villainous gloating towards Preston has the sound of very real malice. He even tells him that he feels.
The man who tests Preston for emotion also utters "Oh shit!" before Preston kills the guards in the room, as do many of guards in the Nethers who utter "Oh fuck!" when Preston unleashes on them.
There could also be an interpretation akin to the RPG Paranoia, where none of the characters are on the meds, and some hide it better than others.
Complete Monster: Vice Council DuPont is the second-in-command of the Librian state under its founder Father. He presides over a totalitarian system in which all human emotions are forbidden and suppressed with a drug called Prozium. Any "sense offenders" who are caught by the elite Tetragrammaton Order are punished with immediate processing and incineration. DuPont executes a plan to destroy the anti-Librian Resistance once and for all by manipulating one of the Clerics to become a sense offender and deliver the Resistance and himself to DuPont on a silver platter for mass execution. This would normally make DuPont another totalitarian agent, but it's eventually discovered that Father has long since died and DuPont is in fact the real undisputed dictator of Libria. Moreover, he's a sense offender who considers himself to be above his own rules, freely indulging in art and literature behind the scenes. Unlike Father, who genuinely believed that he was creating a utopian society, DuPont has the moral conscience to understand the immorality of his actions, yet he knowingly and purposefully abuses the system simply to secure his own power by oppressing millions and slaughtering thousands for a crime he (and his Dragon, Brandt) commit all the time.
Critical Dissonance: This film has a 37% rating on Rotten Tomatoes, but has a score of 7.6 out of 10 on IMDB.
Small Reference Pools: They're burning a painting? Make it the (original) Mona Lisa! Man stumbles for the first time on music? The Ninth Symphony! Just imagine how the movie would've progressed if he'd found a Philip Glass record instead.
Yeah, he'd have gone back on Prozium and wiped out the Resistance singlehandedly.
Special Effects Failure: The face-cutting scene looks as believable as some early Flash/CGI animation. Worse, if you look closely when Preston leaves the room, you can actually see Brandt's face on the floor; it's clearly a photo printed on a piece of paper. (Also, in the photo, he's smiling).
