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.
Complete Monster: Åge Krüger. Killed his daughter in one of the most painful and horrific ways imaginable just because she was an inconvenience to him, seduced and dumped Judith so that (it's strongly implied) he would have a child who he could then physically possess... It's no wonder Mrs. Drusse calls him a demon. Some people would argue that Stig Helmer's responses to the results of his surgical failings are callous enough to make him qualify as one.
Dr. Helmer: Here, Denmark. Excreted from limestone and water. There, Sweden. Carved in granite. Danish scum ... DANISH SCUM!!!!!
Dr. Helmer [later episode] (reaching out towards the Swedish nuclear power plant across the sound): With plutonium we'll get them yet...DANISH SCUM!!!!!
Crowning Moment of Funny: Several, but arguably topped by the way everything that can possibly go wrong goes wrong when the Minister of Health visits the hospital at the climax of Riget I to see "Operation Morning Air" for himself - complete with walking into the middle of an exorcism carried out mid-corridor with improvised tools. Also just about any scene featuring Dr. Helmer.
Ensemble Darkhorse: Despite his Dane-detesting attitude, arrogance and villainy, Dr. Helmer became an instant favourite with the viewers.
Memetic Mutation: "DANSKJÄVLAR!!!" remains a very popular saying in both Sweden and Denmark today.
Moral Event Horizon: Some of the things Helmer does to hide his serious screw-ups might qualify as crossing it.
Narm: Occasionally the timing and special effects can lend some humor; a good example is the unintentionally campy clip of Bongo in slow motion, with red glowing eyes, at the end of episode 2.
