YMMV: Sweet Valley High
- Broken Base: Some laud the Junior High and Senior Year series for showing a more realistic portrayal of teenage life - while others condemn the series as being boring, compared to the earlier series. Still others think that they might be perfectly fine YA series on their own, but with a lot of the major characters from the original series gone, and a whole host of new characters (who would never show up in any of the later series), they just weren't Sweet Valley anymore.
- Sweet Valley Confidential also has broken the base, since it's revelations about the current status of several major characters (most notably Winston and Todd/Jessica) was not what most fans wanted to see happen.
- The TV series. Either it's an entertaining (if wacky) adaptation of the book series, or it's a goofy Saved by the Bell clone with none of the charm that made the books popular.
- Broken Bird: Elizabeth, in Sweet Valley Confidential. Alone in New York, estranged from her sister and basically making her living sneaking into off-Broadway plays for a third rate magazine that reviews off-Broadway plays, and socially isolated from everyone, even the various one-night stands she has.
- Winston as well; in Sweet Valley Confidential, he's gained power and wealth and the ability to get revenge on anyone who ever tormented him. But he's lost everyone who ever cared for him and when Elizabeth rejects him for reformed former tormentor Bruce Putman, he kills himself.
- Butt Monkey: Jessica, of all people. Her schemes and stunts consistently blow up in her face, leaving her humiliated (though given her sometimes malicious intent, this is often deserved). Her genuine efforts at improving herself (music lessons, cooking classes) end up the same way. Virtually everyone, even her own parents, appear to blatantly favor Elizabeth over her—not until she runs away, TWICE, does it finally dawn on anyone how troubled she is. When she aces the SATs, instead of congratulating her, everyone, including her own sister, assumes she must have cheated somehow. Speaking of which, Elizabeth herself frequently treats her like something she stepped in. And the few times she genuinely likes a guy enough to have a steady relationship with him, it never works out.
- Crack Fic: Many outlandish events occurred, but surely The Magic Christmas, in which a pair of harlequin dolls transport Elizabeth and Jessica to
Narniaa fantasy land where they assist twin princes in defeating an evil wizard, must qualify.
- Don't forget the Sweet Valley University book in which one of their professors turned out to be a vampire.
- Creator's Pet/Designated Hero: Elizabeth Wakefield is purported to be the good twin who is nice to everyone - but, more often than not, she comes off as a meddling, sanctimonious hypocrite. As such, many find her to be even worse than the allegedly bad twin, Jessica.
- Crowning Moment of Awesome: Emily Mayer has spent the entirety of the book Nowhere To Run being verbally and emotionally abused by her stepmother Karen. Now, her baby half-sister Karrie is choking and her hysterical mother won't let go of her so that Emily can help her. Emily recalls that when someone is hysterical, the best thing to do is slap them in the face—and she does just that. Ostensibly, this was to save her little sister's life, but most readers chose to hope that deep down, Emily was enjoying getting a little revenge on her bitchy stepmother.
- In Memories Elizabeth is going on about how Steven shouldn't date Jessica's friend Cara when Steven basically tells her to shut up. For readers sick of Elizabeth's sanctamonious lecturing, that moment is a thing of beauty.
- Draco in Leather Pants: Even the writer was amazed at how much fans preferred the "bad twin" Jessica (who fans saw as more understandable and interesting) to "good girl" Elizabeth (who fans saw as hypocritical and self-righteous).
- Ear Worm: "Look right down in the crowded hall, you'll see there's a beauty standing..." You're welcome.
- Ensemble Darkhorse: The Lila Fowler and Winston Egbert fans are quite plentiful.
- Keep Circulating the Tapes: all of the books in The Verse (save for SV Confidential and The Sweet Life) have been out of print for years. The first 12 books of SVH are available in e-book format.
- Likewise, only the TV series' first season has been released on DVD.
- Mary Sue: The twins are, in their separate ways, canon examples.
- Snark Bait: Even many hardcore fans of the series are more than willing to admit that the books are not without their flaws.
