* [[AllAnimationIsDisney All CGI Is Pixar (All Other CGI Is Dreamworks)]]: Doesn't matter if "from the makers of ''IceAge''" is all around the publicity.
* AwesomeArt: Possibly one of the most beautiful looking CG animated films ever made.
* BestKnownForTheFanservice: An animated GIF of the beach ball bouncing off a lady's badonkadonk can be found around the net and for a lot of people it's the most memorable part of the movie.
** Though this wound up as something of a detraction when it became the focus of one of the trailers, as many movie-goers dismissed it as the kind of "crude humor" type film Dreamworks was known to release in the mid-2000's (although Rio is done by Blue Sky Studios) and not the more adventurous film filled with AwesomeMusic that it turned out to be.
* BigLippedAlligatorMoment: Nigel's VillainSong. It comes right out of nowhere, adds absolutely nothing to the story, and is never brought up again. It at ''least'' gives some {{Backstory}} for him and explains why he's evil, but this aspect is never brought up again either, probably to keep the auidience from having any sympathy for the guy when he's clearly meant to be pure evil.
* BrokenBase: Among animation fans. Some see it as [[SoCoolItsAwesome one of the best animated films of 2011]], others find it SoOkayItsAverage, while still others find it a complete and utter ClicheStorm.
* ClicheStorm: The film is a compilation of every trope common to kids movies in the 2000s, especially [[Creator/DreamWorksAnimation Dreamworks]] movies. A LastOfHisKind Blue Bird played by JesseEisenberg whose acting and voice are a MichaelCera stand-in. This Blue Bird [[AcrophobicBird doesn't know]] [[HowDoIShotWeb how to fly]] and is [[{{Adorkable}} awkward and nerdy]] and tries to woo a HotBlooded ActionGirl also LastOfHerKind [[RecycledInSpace bird]] played by Creator/AnneHathaway. A [[IWasQuiteALooker vain]], [[SmugSnake egocentric]], and FauxAffablyEvil bird played by an actor who is not but sounds suspiciously like TimCurry. A HappilyMarried HenpeckedHusband [[TheMentor Mentor]] Toucan played by GeorgeLopez. An OddCouple romance followed by a DieOrFly learning how to fly JustInTime (with the help of the PowerOfLove) scene are both bound to happen.
** {{Troperiffic}}
* CrowningMomentOfAwesome: Linda, driving like a maniac behind the wheel of [[spoiler:a massive parade float]], crashes through a chain link fence onto an airport runway and [[IncrediblyLamePun plays chicken]] with the smuggler's twin-engine plane in a desperate attempt to stop them taking off with Blu. It almost works too.
** And moments later, Blu has several in a row when he [[spoiler: busts out of his cage, frees all the other captive birds, and takes out Nigel -- and by accident, the plane itself -- with a fire extinguisher and a bungee cord, then saves himself and Blue from certain death by flying for the first time in his life.]]
* CrowningMusicOfAwesome: DJ Dero's Batucada in the trailer is only the beginning (and is heavily sampled in the soundtrack). The first two minutes of the movie are set to a Brazilian samba.
** EarWorm
** Nearly EVERY one of the songs in the movie is this.
** Jewel's solo in "Hot Wings I Wanna Party" is one of the most beautiful parts of the entire movie.
*** And a great contrast. Blu's a natural talent at the rapid motions of street-style samba; Jewel's flowing motions evoke a much more formal, classic style of samba.
** John Powell's score is a bit overshadowed by the songs and isn't exactly ''[[WesternAnimation/HowToTrainYourDragon How to Train Your Dragon]]'' but it gets some moments to shine, particularly "Flying" towards the end.
** And now the sequel has Music/BrunoMars featured in it! And he really gets his chance to shine with his introduction song, [[https://www.youtube.com/watch?v=yzoaxnVvtJI "Welcome Back"]], a sweet sounding serenade dedicated to Jewel's return to the Amazon.
** With [[Theatre/{{Wicked}} Kristin]] [[Series/{{Glee}} Chenoweth]] in the film, an awesome song is kind of to be expected. And [[https://www.youtube.com/watch?v=894idIlso5M she doesn't disappoint]].
* DieForOurShip: Poor Roberto's already getting this from Jewel/Blu fans, and the sequel's not even out yet! They're also clearly ignoring the fact that Roberto is repeatedly described by official sources as being a [[NiceGuy genuinely good guy]] who just happens to be a bit of a show off, and while WordOfGod confirms that he's still carrying the torch for Jewel, no evidence has been seen to imply that he's actively trying to undermine Blu and Jewel's relationship. That being said, again, the movie's not out yet, so the fan's outcry ''may'' turn out to be justified when it does, especially considering the fact that Roberto has "a secret" of some kind.
* EnsembleDarkhorse: Nigel.
* FanPreferredCouple: Fanfic writers love shipping [[HoYay Nico and Pedro]].
* GermansLoveDavidHasselhoff: It's not surprising most of its box office came from overseas - even less that Rio's most profitable market outside North America was Brazil.
* HilariousInHindsight: KristinChenoweth is voicing Gabi the Poisonous Tree frog... Who has a bad case of MadLove, can't touch the object of her affection without killing them, and specifically mentions pie in her song describing her current situation. [[PushingDaisies Sounds like Olive finally gets a chance to understand Chuck's situation with Ned "The Pie Maker".]]
* MoralEventHorizon: For Nigel, it's likely forcing a small bird to pick a piece of bird meat out of his beak just so he can try to bite its leg off. And this is in his first speaking part!
* NightmareFuel: Nigel...just Nigel. His FauxAffablyEvil personality does nothing to hide what a truly nasty piece of work he is...particularly if you've attracted one of his many [[IHaveYouNowMyPretty appetites]].
** It certainly doesn't help that he uses a JumpScare every time he appears on screen.
** VillainDecay: In the sequel he's straight-up LaughablyEvil.
* TheScrappy: Roberto is already getting this from fans, even if; or because, he's voiced by Bruno Mars.
* {{Sequelitis}}: The sequel is not as well received as the first.
* {{Squick}}: Any scene where Luiz the bulldog drools on the main characters. Although he has stated it was a medical condition.
%%* UnfortunateImplications: A plot in the sequel is apparently Blue competing over Jewel's affection with a new guy, even though they already ended up together, and with ''children.'' It remains to be seen if it's the actual dilemma of the movie however.
%%** Given the way [[OverprotectiveDad her father]] is depicted, it's possible that he's trying to set her up with a "better man".
%%** WordofGod states that it's mostly paranoia on Blu's part.
