- Base-Breaking Character: Chris Dollanganger; some fans love him and see him as a romantic character, others find him to be a creep with an Oedipus Complex and haven't forgotten him raping his own sister.
- Best Known For The Fan Service: Here's a game: ask a casual reader what they know about the series (or really, Flowers in the Attic). Chances are, the only thing they'll come up with is the BrotherSister Incest angle.
- Contested Sequel: Everything after Flowers in the Attic is contested, with usually If There Be Thorns and Seeds of Yesterday being the most inferior books in the series.
- Most recently though the Diary series has a lot of it. Secret Brother is a big example: Most readers hated it for not answering any questions and generally being pointless, but a few found that it was a decent-to-good story if taken as a stand alone novel and not some sort of Grand Finale it was advertised as. Some people would also diagnose the way to make the Diary series better if the two POV characters are delusional and ignore the whole thing.
- Fanon Discontinuity: The Diary series, full stop. Doesn't help that the ghostwriter brought Cory back to life.
- Harsher in Hindsight: Chris Sr.'s mother Alicia died of breast cancer. Not even ten years after Flowers was published, so did Andrews.
- Internet Backdraft: The reveal that Cory was alive in Christopher's Diary: Echoes of Dollanganger did not sit well with fans, some calling it outright insulting to Andrews.
- The Woobie: If you don't feel sorry for Carrie, you have no soul. Also Cory and Bart, for all his creepy tendencies.
- Bart in particular becomes much more sympathetic if you have experience with mental illness. Bart has very obvious shades of BPD or AVPD, blacks out fairly often and is often terrified by his own intensely violent urges. He uses an extremely misogynistic form of Christianity to justify lashing out at his mother's favoritism of his older brother, and could easily be separated from it if his parents gave a damn. Even though its probably one of the few fictional instances where a character being institutionalized would help rather than harm them, Bart's never helped beyond lukewarm therapy, and grows up with a skewed sense of love, family and intimacy as a result.
