* ClicheStorm: 3D's plot is every low-budged sports/competition convention thrown in, complete with the two rival team's lead dancers being former friends that had a falling out.
%%* EarWorm
* EnsembleDarkhorse: Camille from the first movie and Moose from The Streets. Naturally people were happy when they were brought back for the third and they were even PromotedToLoveInterest for each other
* {{Fanon}}: Camille's relation to Tyler is not concrete. At most the two are half-siblings because she mentions her dad being in prison, but fans decided that they were related and producers decided they agreed.
* FanPreferredCouple: Andie/Blake from The Streets
* FunnyAneurysmMoment: ''Revolution'' features a scene of the heroes crashing the villain's party, where they throw in smoke bombs and then dance around while dressed completely in black with gas masks, to a song that includes gunshot sound effects. It's rather jaw-dropping that the studio didn't feel the need to remove this scene after the massacre at an Aurora, Colorado screening of ''Film/TheDarkKnightRises''.
* JustHereForGodzilla: Quite a few people only saw 3D because [[EnsembleDarkhorse Adam Sevani and Alyson Stoner]] were in it and don't care for the main plot
* ReplacementScrappy: Many fans were upset that [[RememberTheNewGuy Andie]] was the star of The Streets rather than Camille
* {{Sequelitis}}: Averted, Step Up 2: The Streets was better recived by critics for having a better plot and better dancing than the first movie. Step Up 3D, despite having a more {{Troperiffic}} plot, [[TropesAreNotBad was even more well recieved.]]
* TheyWastedAPerfectlyGoodPlot: 3D features the return of Camille Gage, Tyler's sister. However this is never mentioned at all. They could have had her feel like she's in his shadow because he's a famous dancer. They also could have had some sort of flashback featuring the start of her friendship Moose or even started the movie with it before doing a flashforward
