YMMV / The Family That Preys
Alternative Character Interpretation: Was Chris really unaware of his wife's cheating or was he in denial? Or just plain stupid?
Anvilicious: Not nearly as bad as Perry's usual films, but it lays it on pretty thick about adultery.
Designated Hero: Pam. Granted, yes, she is the more faithful daughter and the better wife between the two sisters, but she's still snooty in her own right. She doesn't like looking after her nephew and was downright dismissive and condescending to Nick, even after learning about his sad past.
Family-Unfriendly Aesop: Achieving the highest level of success means becoming morally bankrupt and acting ruthless to everyone around you in the process, especially your mother and your spouse. That, and people should not date outside of their race. Granted, William and Andrea did engage with one another under awful circumstances that can't be defended (both were married to other people and the whole Ambition Is Evil thing), but Jillian telling her that William's business associates would drop him if he showed up in public with her most likely stung pretty badly for any and all interracial couples in the audience.
Marty Stu: Chris, to the point of almost sickening levels. Well, at least until the climax of the film...
Tear Jerker: The movie itself with Alice and Charlotte, especially when it ends with Charlotte's death.
What an Idiot: Even when the truth was staring him right in the face, Chris still is blissfully unaware of Andrea's cheating.
The Woobie: Chris.
Alice and Charlotte (although they qualify as iron woobies.)
