Denise Huxtable vs. Mary Camden from "7th Heaven"

[TMC]

Which once great teenage girl character endured the worst case of "character assassination".

Before Lisa Bonet appeared in the film Angel Heart, which included nudity and a sex scene, Denise was a cool, laid-back, and outspoken girl. But after Angel Heart, Denise's character became braindead and flighty. Even worse, she was now also a stepmother to little Raven-Symone, who stole the spotlight.

Meanwhile, Mary on 7th Heaven, started off as being a mature and responsible teen who sometimes rebelled but ended up doing the right thing. But after Jessica Biel posed provocatively for a men's magazine, her character devolved into being a dysfunctional, selfish mess, who got dishonorably written off due to being kicked out of her home to live with relatives because of her bad behavior. And when even when Mary comes back, she's now an airhead who can't get things right.
