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.
Sander Cohen and Martin Finnegan murdering three innocent people.
Dr. Steinman operating on someone after he's gone mad. He rips her face off.
Harold Babcock and his wife getting electrocuted in a plasmid fight.
Squick: Tenenbaum having rough sex with Fontaine. Bleh.
Sander Cohen and his infamous act of forcing a youth to screw an octopus at a wild party.
They Wasted a Perfectly Good Plot: To a degree considering just how many stories the novel tries to contain and share. Because of the book's rushed state to incorporate lore from BioShock 2, many notable characters from that game have a diminished presence. There's also several off-page events, be they due to being in-game materials (such as Audio Diary events) or simply not being portrayed on the page.
The Woobie: Bill McDonagh and his family. Even moreso in how they manage to escape, but he does not.
