* AcceptableTargets: Good ''lord'' does Sweet Valley hate the overweight. They're portrayed as dumpy, shuffling, pathetic nerds who only want to be accepted by the Beautiful People who hate them. The worst example of this is Robin Wilson, who's tormented by the cheerleaders and is only accepted after losing a ton of weight, only to develop an eating disorder.
* BrokenBase: 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 [[PutOnABus a lot of the major characters from the original series gone]], and [[ReplacementScrappy a whole host of new characters (who would never show up in any of the later series)]], they just [[InNameOnly weren't Sweet Valley anymore]].
** Sweet Valley Confidential also has broken the base, since its 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 Series/SavedByTheBell clone with none of the charm that made the books popular.
* CrackFic: Many outlandish events occurred, but surely ''The Magic Christmas'', in which a pair of harlequin dolls transport Elizabeth and Jessica to [[strike:Narnia]] a fantasy land where they assist [[SpearCounterpart 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.
** 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 sanctimonious lecturing, that moment is a thing of beauty.
** In ''Outcast'', a secondary character tells Elizabeth to "shove it". ''Also'' a thing of beauty for those sick of her self-righteousness.
** And yet another beautiful moment in one of the super editions when Jessica blasts Elizabeth for her rudeness towards a new male character, telling her she's " the worst kind of reverse snob", truthfully pointing out that just because the guy is rich, it doesn't automatically make him a bad person.
* DesignatedHero: Elizabeth 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.
** Big brother Steve isn't much better. He's frequently a complete jerk to Cara, incredibly cruel at times--publicly humiliating her on several occasions--without any provocation or justification and cheats on her twice with girls who are the spitting image of his dead girlfriend Tricia Martin. Adding insult to injury, this is the only reason he's interested in them. But this all supposed to be OK, because, "Poor Steve, he just loved Tricia and misses her so much."
* DesignatedVillain: Conversely, Jessica is consistently portrayed as a bitch, even though she [[JerkassHasAPoint actually has a point]] on several occasions. Elizabeth blasts her for being horrible to Winston Egbert and not giving him a chance, but Jessica has made it abundantly clear that she does not reciprocate his feelings for her. And instead of accepting this and moving on, he persists in pursuing her. Who wouldn't be annoyed at that?
* DracoInLeatherPants: 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).
* EarWorm: From the opening tunes of the TV series: ''Look right down in the crowded hall, you'll see there's a beauty standing...''. And its refrain: ''Sweeeeeeeet Valley, Sweeeeeeeet Valley High...''.
* EnsembleDarkhorse: The Lila Fowler and Winston Egbert fans are quite plentiful.
* MarySue: The twins are, in their separate ways, canon examples.
* SnarkBait: Even many hardcore fans of the series are more than willing to admit that the books are not without their flaws.
** The members of the wonderful [[http://1bruce1.livejournal.com 1bruce1]] community on Website/LiveJournal have snarked nearly every book and TV episode.
