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.
Designated Evil: Esther's mercy-killing of the accidentally, mortally wounded bird, is presented as a cruel/heinous act.
Rooting for the Empire: It's easy to root for Esther despite the fact she's batshit insane because A) She's a Magnificent Bastard and B) Isabelle Fuhrman's performance. Not to mention most of the protagonists- except for maybe Max come off as whiny and annoying to some.
Squick: When Esther tries to seduce John in a cocktail dress.
Esther breaking her own arm, especially as the bone very visibly pops out. The fact that it's the only scene where she shows any real weakness or pain somehow makes it worse.
Hilarious in Hindsight: An episode of Dr. Katz, Professional Therapist had Dr. Katz and his son humorously discuss horror movies where the killers were midgets. Titles (to the best of my memory) included "I'm Short, But You're Dead" and "Don't Step On My Toes, Or I'll Kill You!"
