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.
Ugly Cute: While a lot of people find the stitchpunks adorable, some of their designs are a bit... unusual and creepy to some.
Bowdlerise: Many fans have expressed... disappointment with the edited version aired on SyFy and USA. Apparent edits included removal of dialogue, removal of the light staff building scene, and removal of the factory chase scene.
Cargo Ship: There is someone out there who ships 1xHis Cape. Dead serious here. 8xHis Sword also exists. As does 8xHis Magnet.
Did you see the look on his face? 8xMagnet is canon.
Crack Pairing: Since it's got so few characters and everybody is a machine, anything and everything has been shipped together, mostly for laughs. Pairing male characters together is of course the most popular practice, and probably a given since the majority of fans are female. 6, being an Ensemble Darkhorse, is the one most subject to pairings, mostly with 5 or 9. See Ho Yay, Launcher of a Thousand Ships, Ship Tease and Slash Fic below.
Crowning Moment of Heartwarming: 2 seems to be a living manifestation of this trope. And just try not to smile when 1's soul silently thanks 9. Oh, hell, just the entire scene when the fallen Stitchpunks' souls are freed.
There's also the deleted scene after the factory is destroyed where 1 makes amends with 9 and accepts him after admitting he's not as good of a leader he had made himself out to be. Immediately followed by a Crowning Moment of Funny when his crown falls off and reveals the silly little knot on his head, which both 9 and 1 laugh at.
He's also called "Creeper2" by some on Deviantart.
There's also Pedo9, which originated from a very creepy looking figurine made before the movie came out. You don't want to know what it looked like, believe me.
Fanon Discontinuity: The Russian version. It's not 'all' bad and some people do like it, and it does have some changes to the plot that are an interesting idea (such as the characters being the souls of the scientist's friends and family instead of pieces of his own soul). However, it makes so many other changes to the movie that most who have had the chance to see it would rather they just forget it exists.
Ho Yay: It breathes this trope. Come on, only one character (7) is distinctly female, and two (3 and 4) might be interpreted either way. It's practically canon. 5 and 6 especially seem to be a magnet for this.
It Was His Sled: Since promotional videos released before the film showed the Seamstress, with 2's body strung onto her tail, it's generally common and open knowledge that 2 dies. Especially since it happens very early in a relatively short movie.
Narm Charm: The "Somewhere Over the Rainbow" sequence is really, really over the top. That doesn't stop the payoff from being terrifying.
Relationship Writing Fumble: It's amazing how many fans saw more chemistry between 9 and 5 than between 9 and 7. Then again, that's probably founded upon overthinking, and it was never canonically established that 9 and 7 had romantic feelings for each other in the first place. The implications were based on one or two shots of them holding hands. And since they're really just little dolls, it's perfectly likely that their relationship was platonic and childlike.
Ship Tease: 7 and9, 5 and 9, 5 and 6, 5 and 2. Many more, if the fandom is anything to go by.
Tear Jerker: The whole movie. Especially 2's funeral, what happens right before the end (sad) and the end (happy?).
1's last words. He may have acted like a Jerk Ass for most of the history, but his declaration that "They left us with Nothing" really puts in scope that he's VERY bitter with being abandoned in a dead planet with machines hunting them down because of the Chancellor's greed. Try to imagine this: You're left with only a few others like yourself, after surviving a war caused by a single human's misdeeds, in a completely destroyed and dead planet with horrifying creatures that want to kill you for your souls, and you alone are left with the task of protecting them, while being the size of a toy. In a way, 1 is a Shell-Shocked Veteran who's been pushed way over the Cynical side of the scale.
What Do You Mean, It's Not for Kids?: A disturbing number of idiots who brought small children along, despite the commercials clearly stating it was not a children's animated movie. Most were in tears by the middle of the film.
And it's rated PG-13. Though, the movie's genre is labeled as Kids & Family. Kind of surprising, considering the fact that a total of nine sentient beings (1, 2, 5, 6, 8, Mr. Fab, the Cat, the Winged, and the Seamstress) get brutally killed over the course of the movie.
