* 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 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 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.
* CrowningMomentOfAwesome: 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.
* DesignatedHero: 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.
* 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: "Look right down in the crowded hall, you'll see there's a beauty standing..." You're welcome.
* EnsembleDarkhorse: The Lila Fowler and Winston Egbert fans are quite plentiful.
* KeepCirculatingTheTapes: 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.
* 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 LiveJournal have snarked nearly every book and TV episode.
