* AlternativeCharacterInterpretation: [[https://muppetmindset.wordpress.com/2010/01/12/its-not-easy-being-mean-part-1/ This article]] posits that Doc Hopper isn't a JerkWithAHeartOfJerk so much as someone intended to be dark reflection of the Muppets and especially a {{Foil}} to Kermit. It notes that he has several of the same characteristics that the Muppets have and that ultimately he does briefly consider a better way before recognizing his own dream won't allow him close friends like Kermit has.
* AwardSnub: "Rainbow Connection" lost the Oscar for Best Original Song to the now-virtually-forgotten "It Goes Like It Goes" from ''Film/NormaRae''.[[note]]Which, it must be noted, deserved quite a few awards, but "Best Song" is not on that list.[[/note]]
* AwesomeMusic: Paul Williams' score is packed with this.
** "Rainbow Connection" will hit you as either {{Narm}}tastic or one of the most inspiring songs you've ever heard. [[NarmCharm Or both.]]
* CrowningMomentOfHeartwarming: The big finale song "Magic Store".
-->''Life's like a movie\\
Write your own ending\\
Keep believing\\
Keep pretending\\
We done just what we set out to do\\
Thanks to the lovers\\
The dreamers\\
and YOU!''
** "Prepare the standard 'Rich and Famous' contract for Kermit the Frog and company."
** "[[CrowningMusicOfAwesome I'm Going To Go Back There Someday]]"
* DudeNotFunny: There ''are'' wineries in Idaho, and they didn't see the humor in Steve Martin's "sparkling Muscatel" bit. Then again, Muscatel is ''not'' produced in Idaho, which specializes in seasonals like Reisling and Chardonnay.
** Also, keep in mind that in 1980, wine made in places other than France or Italy or whatever (for example, California wine) was seen as a joke or mediocre. Nowadays, it's different. That said, to most folks outside of Idaho, ''wine'' is not something that comes to mind when that state is mentioned. [Hint: The state license plate says "Famous Potatoes".] Additionally, the wine bottle had a ''bottle cap''.
* EarWorm: "Rainbow Connection", "Movin' Right Along"
* FirstInstallmentWins: The Muppet features that followed have their fans and are certainly beloved in their own right, but the one that started it all is almost universally considered the best.
* HarsherInHindsight: Kermit imagines thousands of other frogs going around with tiny crutches. Real-life wild frog populations have suffered a decimating rash of leg deformities in the years since the film was made, some from pollution and others from natural parasites or predators.
* HeartwarmingInHindsight: The behind-the-scenes picture of Steve Whitmire goofing around with a Kermit puppet.
* HilariousInHindsight:
** It only took 40 years, but Western stars are [[http://timesofindia.indiatimes.com/entertainment/hindi/bollywood/Top-10-foreign-actresses-in-Bollywood/photostory/24691995.cms finally making it big in Bollywood,]] making this exchange that much funnier.
-->'''Gonzo:''' I always wanted to go to [[UsefulNotes/{{Bollywood}} Bombay, India]], and become a movie star.
-->'''Fozzie:''' You don't go to Bombay to become a movie star. You go where we're going, Hollywood!
-->'''Gonzo:''' Sure, if you want to do it the ''easy'' way.
-->'''Fozzie:''' We've picked up a weirdo.
** Kermit's reasoning for not doing the frog leg ad is because he can imagine [[AnArmAndALeg frogs with tiny crutches.]] Years later, his nephew Robin plays the crutch-toting Tiny Tim in ''Film/TheMuppetChristmasCarol''.
* MoralEventHorizon: Crossed by Doc Hopper during the climax. "All right, boys... kill 'im."
** Jim Henson actually wanted Hopper to be redeemed at the end, but Oz overruled him.
* NightmareFuel:
** Doc Hopper's frog suit in his commercial is kind of creepy.
** Also, the idea of Doc Hopper threatening Kermit and wanting to make him a frog burger is really unsettling.
** Professor Krassman's electronic cerebrectomy machine.
*** Not to mention when Krassman himself becomes the [[HoistByHisOwnPetard victim of said machine.]] Granted, [[AssholeVictim he deserved it,]] but still... we see him ''screaming in agony as the machine lobotomizes him.'' (Shudder)
** Miss Piggy's [[http://images.wikia.com/muppet/images/a/a9/MadEyedPiggy-TMM.jpg wide angry eyes]] when she karate-chops the kidnappers-- though it also has an air of ComicalAngryFace.
** It doesn't help when she's above them and says, "Oh, boys." When the camera pans up to her, she looks like a creature out of hell!
* OneSceneWonder: Numerous examples (Creator/SteveMartin's [[ServileSnarker waiter]], Creator/MelBrooks' [[MadScientist Krassman]]) but taken UpToEleven with Creator/OrsonWelles' cameo as Lew Lord, who's not only in just one scene but has exactly ''one line'', yet manages to be one of the most memorable characters in the film.
* SeinfeldIsUnfunny: Alas, many of the jokes and wackiness have been copied by countless followers (both ''Film/Gremlins2TheNewBatch'' and ''WesternAnimation/TheSpongebobSquarepantsMovie'' have done meta gags about their films being watched in theaters, for example), that, to anyone watching the film for the first time, it might seem less remarkable.
** That meta gag had been used, to hilarious effect, in ''Film/BlazingSaddles'', five years prior to this film.
* SoBadItsGood: Doc Hopper's ad.
* SweetDreamsFuel: "Someday, we'll find it/The rainbow connection/The lovers, the dreamers/And me..."
* VisualEffectsOfAwesome: Kermit riding a bike near the beginning. Don't wonder how they did it, just accept it.
** Actually, according to Frank Oz, the effect was relatively easy to do,[[note]]Essentially, the Kermit riding the bike was a marionette, with the bike pulled along by an invisible wire[[/note]] compared to the monstrous effort required to get Gonzo to float along on his balloons. But since the bike was the effect everyone kept gawking over, they included an entire parade of Muppets on bikes in [[Film/TheGreatMuppetCaper the next movie.]] Just because.
** Plus Kermit in the swamp, which was created by the 6'1" Jim Henson cramming himself into a diving bell for a whole day.
* WhatDoYouMeanItsForKids: Played with. It isn't ''in''appropriate for children or families, but is clearly meant to be viewed as any other Hollywood feature which just happens to star puppets (indeed, Jim Henson himself always saw the Muppets as more of a theater troupe than as characters). Still, it was not an easy pitch to sell.
