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: Marissa Wiegler is even more ruthless than her henchmen, even Issacs, which is fitting considering she could be considered one of the most depraved and sadistic madwomen in film history. To start, Marissa terminated the Super Soldier program, killing 19 out of 20 children along with their parents. She follows this by ambushing and killing Hanna's mother as Hanna and Erik escaped to the forests. After systematically hiding her nefarious program details from her colleagues and killing Hanna's grandmother, she captures and presumably kills Sophie and her family... (She would've definitely qualify for this big time, if Sophie and her family were really killed and mentioned in the body count) and she enjoyed every second of it. Her death at the very end gets an added touch with an echo from the beginning of the film. All in all, she's arguably one of the most depraved and sadistic madwomen in film history.
Fridge Horror: Sophie and her family were likely killed after Marissa and her cronies interrogated them, considering that's the fate met by everybody else they've questioned. In that case, it would be another candidate for Marissa's Moral Event Horizon, especially since Sophie and her brother are just innocent children.
Well, the original script has it that they survived, so that's something of a relief.
Hilarious in Hindsight: The hapless and defenseless Susie Salmon has been reincarnated into a nearly unstoppable killing machine who eats trained adult soldiers and skinheads for breakfast.
