History YMMV / TeenBeachMovie

* HilariousInHindsight: [[Series/AndiMack Never write a song for a girl named Mack.]]

* FridgeBrilliance: Abound. Just to name a few:
** When they're in the "real world" Mack and Brady actually ''surf''. In the "movie" portion, Mack and Tanner are [[DrivingADesk surfing in front of a green screen]].
** When the movie, ''Wet Side Story's,'' projected on to a screen, or shown on a TV screen, it's shown with a warmer color pallet indicative of older films, pre-2008, that were shot on older film cameras with older film lenses. However, when we're looking into the film universe, it looks more like the world outside the film. Most likely because we're supposed to be seeing the film universe as it was when it was shot, rather than through the remastered film stock it would've gone through in-universe.
** A few plot holes tend to show up, especially towards the middle-end. [[spoiler: How did Tanner and Lela find out about Camembert's and Dr. Fusion's evil plan?]] Of course, 1960s surfing movies had their fair share of plotholes too so it's easy to assume that the actual ''Wet Side Story'' likely had the same plotholes as well. Plus, it could be a side effect of the movie essentially trying to catch up with itself once the plot is un-derailed.
*** Likewise, this does explain why the plot of ''Wet Side Story'' in the first film moves very quickly, why Camembert and Dr. Fusion never return in the sequel despite hinting they would and why there's no explanation about [[spoiler: What ''Wet Side Story'' becoming ''Lela, Queen of the Beach'' could do to the timeline or the very fabric of reality itself]].
** The opening theme is set in the present and [[AutoTune Autotuned]], but the rest of the songs are not because they're from the 60s and Autotune didn't exist yet.
** When in the real world in the second movie, Lela and Tanner can influence the real world, as evidenced by the few songs they have before their friends follow them. Considering their hair still doesn't get wet, and any clothes they wear transform into their 60s equivalents for a while, it can be assumed they still have the movie's magic as a part of their beings until they'd ultimately disappear. It doesn't make as much sense for Mack and Brady when they do the 'Silver Screen' song, but they could possibly be tapping into the bit of residual movie magic they might've gained from being in the movie to perform it.
*** 'Silver Screen' make sense in the other direction without movie magic though. The movie magic is gone by that point, as seen Tanner and Lela now being bound by the physics of this world. However [[spoiler:immediately before the song, Brady and Mack were trying to convince Lela and Tanner that they are movie characters to no avail. Brady has the idea of illustrating his point “in a language they can understand,” that is, a song.]] Hence this number is Brady and Mack actually arranging a crew for the song.

** Ramped UpToEleven in ''Teen Beach 2''.

* RelationshipWritingFumble: In the second movie, Lela and Mack are supposed to be friends and straight with boyfriends. However, Lela begins the movie basically ignoring her boyfriend Tanner and seemingly pinning over Mack. When she finds Mack's necklace, Lela readily abandons her whole life, including Tanner if he hadn't followed, just to see her again. When first arriving in the real world, she's overly excited to wear Mack's clothes and model for her, while acting like a teenage girl in front of her crush. Lela hangs out with Mack to the point that Tanner gets jealous, and then refuses to leave her new life and seemingly Mack behind. Lela ends the film by throwing Mack her jacket and winking at her. For Mack's part, she seems starstruck when she sees Lela look "normal" for the first time, with her mouth hanging open. She encourages Lela to rewrite the movie, and in the alternate timeline is obsessed with the movie ''Lela, Queen of the Beach'' even more than Brady was with ''Wet Side Story''.

* AlternativeAesopInterpretation: The second movie's ending [[spoiler:doesn't erase the events of everything that came before with Leila changing the movie, but instead, it's translated into an alternate universe WhatIf scenario that shows Mac and Brady still finding their way to each other no matter what. That would also lend to the idea that the main storyline still allows not only for that version of Mac and Brady to still have their previous history not be forgotten or undone, but that it keeps the [[AmbiguousEnding uncertain while hopeful]] feelings they still have a about their relationship moving forward too]].

** If they don't make a third movie, the fact that there's changes to the universe of the movies due to Lela changing ''Wet Side Story'' to ''Lela: Queen of the Beach'' surely had more repercussions than just Mack and Brady never meeting and erasing Brady's favorite movie from existence. The fabric of reality could be at stake or something for all ''we'' know, especially with all the plotholes that ending brings to mind.
* UnfortunateImplications: The ending of the second movie is ''rife'' with them. First, while it's perfectly in-character for Mack to encourage Lela to do what makes her happy, her encouraging her to change the movie before she goes back causes a ''big'' butterfly effect where history changes and she and Brady no longer know each other. She obviously knew this would happen, or she wouldn't be seen as forlorn as she does before history changes. So, did she really love Brady like she claimed, or no? Second, the entire point of the first movie is negated because she changed history. Third, a ''lot'' more than just their lives would change from history changing. Fourth, people who were invested in the first movie and the second movie until the ending are supposed to be happy because the characters are still alive, even though they'd be very different people and don't know each other? Really? There are way too many questions asked from the ending and it's frustrating. Even the socio-political changes ''Lela: Queen of the Beach'' might've made, being a feminist movie now, back in 1962 are left up in the air.

* ValuesDissonance: [[InvokedTrope Invoked]]:
--> '''Mack:''' Why does she need a boy to make her happy?
--> '''Brady:''' Because it's 1962!
** The values dissonance between the two worlds becomes a central plot point in ''Teen Beach 2''.

* SignatureSong: “Srf’s Up” from the first, “Gotta Be Me” from the second.

* OneSceneWonder: [[spoiler: Music/JustinBieber]] makes a surprise cameo at [[TheStinger the very end of the movie]]. The reaction it gets from the characters is ''priceless'', especially if you don't like him. (It's actually a picture of him as someone's homescreen picture on their smartphone.).

** A few plot holes tend to show up, especially towards the middle-end. [[spoiler: How did Tanner and Lela find out about Camembert's and Dr. Fusion's evil plan?]]. Of course, 1960s surfing movies had their fair share of plotholes too so it's easy to assume that the actual ''Wet Side Story'' likely had the same plotholes as well. Plus, it could be a side effect of the movie essentially trying to catch up with itself once the plot is un-derailed.

** This is partly also partially brought on through the fact that the ending of the second film overrides one of the main messages they were trying to tell, in that [[spoiler:Mack is happy to be with Brady and came to like ''Wet Side Story'' like he did, and defying what she thought was expected of her to stay in their city to be with him rather than be miserable in a life of academia, which she could easily do other things for after high school. The main motif of the films even became what the song 'Meant to be' is about, in that if you know someone is the one, you should be with them. Mack threw all of that away to change the timeline in ways that she knew would prevent her and Brady from ever meeting for the reason that Lela is someone who was born in the wrong time rather than be happy with her life as it was.]] Was it a bold move? Yes, but the right one? Probably not.

* FanPreferredCouple: The Lela and [=McKenzie/Mack=] pairing is far more popular than their canon pairings with Brady and Tanner, due to their expanded relationship in the second film and the LesYay between them through both films. They have the [[https://archiveofourown.org/tags/Lela*s*McKenzie%20(Teen%20Beach%20Movie)/works most fics]] about them on Website/ArchiveOfOurOwn, with 21 for them together verses 4 for Mack with Brady and 3 for Lela with Tanner.
