These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Acceptable Targets: The Muppets figure it's okay to kidnap Jack Black to host the show, because "a celebrity is not a people". Although, Lew Zealand says this, so the thought may not have been shared by all. Kermit was openly against it.
No one’s gonna stop this girl from having fun I throw my hands up high and have a party for one — I'm not gonna sit around by myself and wait for you Haven't you heard one is the new two? — And what happens at the "me party" Stays at the "me party"
Also the fart shoes. The DVD commentary says that the only reason they introduced the fart shoes was to have the farting noise as Fozzie walked out of the theater.
Frank Oz refused to work on the film due to this joke, seeing it as emblematic of the writers not getting what made the Muppets work. Though others have responded that he seemed to have rather missed the point that Fozzie's schtick has always been that he's a bad comedian, and this kind of thing is exactly what he should be doing these days.
The thing of it is, the Muppets' humor, even Fozzie's pathetic attempts at comedy, was always sophisticated and intelligent, fart shoes (and fart jokes, in general) is pretty low-brow, even by Fozzie standards.
"Me Party" doesn't advance the plot, and Mary might have taken too much of it for herself, but it's dang catchy.
Crazy Awesome: Gonzo. Okay, it's really no surprise coming from him, but he takes it to new heights when it's revealed that he's not only been expecting a reunion and thus had been wearing his stage outfit under his suit for years, but he also had an automatic Self-Destruct Mechanism for the big business he's been in charge of.
Critical Dissonance: One of the most frustrating examples. The Muppets was one of the best-reviewed movies of 2011 and most who saw it did in fact praise the film. Unfortunately, most general audiences seemed to think Breaking Dawn and Alvin and the Chipmunks: Chipwrecked looked like the superior movies and saved their money for those, leading to a solid but not certainly great box office total.
Dead Unicorn Trope: When Kermit and the gang are trying to break into Piggy's office and fail, they decide to use "Muppet Man" to get past the door. "Muppet Man" turns out to be the whole group of them squeezed into a suit, akin to when the Little Rascals attempted to pass themselves off as an adult. This is played as though it's something we're all used to seeing the Muppets do, including Fozzy simply declaring "Hey, everyone! Muppet Man!" as though we all know what that is, and having Piggy react with "I can't believe I fell for Muppet Man!" Muppet Man has never been used before.
Ear Worm: Life's a happy song, when there's someone by your side to sing along.
In the actual movie, during the "Man or a Muppet?" song, Walter looks in the mirror and sees what he would look like as a human: Jim Parsons. This got funnier when Jim Parsons revealed that he is homosexual, considering Gary and Walter are definitely Heterosexual Life-Partners.
Actually the two are brothers even though Walter was probably adopted
Like You Would Really Do It: Double Subverted. The Hail Mary telethon fails, the magic fix at the end falls through, and Kermit's ready to start the group again from the ground up, with whatever fans they have left, no studio and no Muppet name. If it wasn't for the fact that the fandom came in droves, and Gonzo's bowling ball makes a rather persuasive argument towards Tex Richman giving up his claim on The Muppet Show studio, this would have easily been a very subverted trope.
Narm Charm: The Swedish Chef's gibberish during the movie's more sentimental moments, like "Pictures In My Head" and after the telethon ends and the Muppets failed to raise the $10,000,000.
Swedish Chef:(sadly, while cuddling the chickens) ...Chickee.
"Gary, I love you, but you have to decide: Are you a man, or a Muppet?"
Nightmare Fuel: Bunsen and Beaker were working on the Large Hadron Collider. Yeah, it was just them doing the usual science stuff, but when you remember how questionable their skills can be... would you really trust them with something of that magnitude?
One-Scene Wonder: The human version of Walter, as played by Jim Parsons in one of the best unexpected cameos in any Muppet film.
What Do You Mean, It's Not Political?: Many people on more conservative news shows were upset that the villain was a CEO who wanted to drill for oil, saying that the Muppets were promoting class warfare for children. They apparently hadn't watched the film, since it later becomes clear that Tex Richman is evil not because he is a CEO, rich, or wants oil, but because he is unable to laugh and laughter, aka the third greatest gift ever, is necessary for happiness. He also decides to turn the Muppet name into a cynical, depressing act For the Evulz, which doesn't have much to do with oil. ...though, anything concerning his back story was cut, which does not help any!
As well as the fact that any five-year-old would know he's a caricature just by the name and Large Ham tendencies.
To say nothing of the fact that Kermit is himself a CEO of The Muppets as an incorporated entity — and while not stinking rich, was still well off enough to be living in a swanky house and keeping it in good repair. So it was one corp guy against another corp ... er, frog.
In fact, paying more attention reveals that Gonzo was rich in the movie, but his disruptive behavior prevented him from buying out the theater — he had the money, and blew it up in his enthusiasm to return. Far from class warfare, the movie paints Gonzo as caring about the Muppets nearly as much as he cared about Camilla's feelings. Similarly, Piggy's portrayed as well-off, but never flaunts this beyond the vanity that's been part of the character since the original show.
In a Take Thatvideo, the Muppets respond that they are not involved in brainwashing children and compare the hysteria to saying that the public media is "accusing Fox News of being just... news".
The Woobie: Walter and Kermit, big time. Walter is trying to save the Muppet name and finding his special talent under so much pressure... it's pretty sad to see the poor guy struggling. Meanwhile, Kermit has to jump through hoops to get the gang back together, raise enough money to save the show, and gather the courage to admit to Miss Piggy his feelings. It's so much pressure for a little green frog.
