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.
Magnificent Bastard: The Acheron's captain, a skilled commander, capable deceiver, and all-around Worthy Opponent for Jack. Oddly enough, he's The Faceless aside from the scene where he impersonates one of his own men - his name and personality are virtually unknown. But then, that's war for you.
Nausea Fuel: The surgery scenes in this film. Only Stephen manages to keep anything close to a straight face while at work even on himself. The other characters who have to assist him in these procedures show evident signs of being uncomfortable and borderline nauseated at what they're seeing.
