Nightmare Fuel: Toy Story 3
Watching your icons futilely struggle for their lives.... "Toys don't last forever," indeed.
Lotso, full-stop. On the outside, he's a caring stuffed bear who looks after all the other toys at Sunnyside. On the inside, he's a sociopathic Nietzsche Wannabe who not only doesn't give a second thought to sending new arrivals to the Caterpillar Room where they'll inevitably be used until they're ruined and sent to the dump, but is so bent on doing so that he's turned Sunnyside into a nigh-inescapable prison where he rules with an iron fist through lies, abuse, surveillance, coercion, and even brainwashing - all for the sake of forcing his nihilistic worldview upon everyone he possibly can as a self-validating coping mechanism for the heartbreak his former owner put him through. Even Woody, after he and the others escape the incinerator, considers Lotso too far gone to be worth the trouble.
Speaking of the brainwashing, there's what happens to Buzz. Considering that he's been one of the most heroic characters of the series, watching him be overpowered and turned evil (particularly after his Character Development in the first film) and then ruthlessly help imprison his friends is pretty unsettling. The reveal, in which Buzz emerges from the shadows in front of Jessie, even resembles something from a horror film.
Especially chilling is the slow zoom-in shot of Lotso smiling Kubrick-style and leaning on his cane, while the only thing the audience has to go on is a few fleeting glimpses of Buzz darting around in the foreground and the sounds of him single-handedly dispatching his friends.
The scene wherein we realize just how short a lifespan any toy assigned to the Caterpillar Room can expect.
The thought of spending the night locked in the Box must be quite daunting to any viewers with a fear of confined spaces. Not to mention Jessie.
The scene where Woody tries to escape Sunnyside on a kite but is caught by an upward draft is punctuated by a first-person perspective shot looking straight down at the ground several hundred feet below. Yikes.
The resolution of the scene is even worse, given some Fridge Logic: How lucky is it that Woody's string doesn't snap when it snags on that tree branch? To make matters worse still, Bonnie simply yanks him downward when she finds him instead of bothering to pull him off the branch gently.
The cymbal-banging monkey. Creepy enough already, but things go Up to Eleven fast whenever it sounds the alarm. And dear God, the scene where Woody and Slinky ambush it...
The landfill sequence as a whole, in fact. First, we get Buzz being crushed by a TV in a garbage truck. He survives, but it's unnervingly easy to imagine things not turning out so well. Next, at the dump, the comic relief aliens get run over by a bulldozer. Then the toys come very close to being torn to shreds by the crusher - especially Lotso, who is trapped beneath a large piece of trash. Woody and Buzz save him, at great risk to themselves, but when Lotso is given the chance to redeem himself by stopping the conveyor belt, he instead tops it all off by betraying the toys and leaving them to die.
Worst of all is the Hope Spot just after the toys escape the crusher: Rex looks ahead to the conveyor belt's exit and declares that he sees daylight, and the toys share a well-earned moment of celebration. And then the music changes as Woody's face falls.
Lotso's Dragon, Big Baby. Pixar invokes the Uncanny Valleybrilliantly with this lazy-eyed Terminator of an oversized doll.
It's hard to decide which part of the swing scene is the creepiest: Big Baby staring motionlessly up at the sky, spinning his head around 180 degrees with terrifying speed, or keeping his head fixed in that direction as his body pivots around it.
The Chatter Telephone has been at Sunnyside for an untold number of years by the time of the film, but has never been broken. This lends his defeat near the end of the movie all the more impact, especially since we only see the cringe-inducing aftermath of the Cold-Blooded Torture the movie implies Lotso's thugs put him through, but leaves us to imagine for ourselves.
Lotso is resigned to what may well be a Fate Worse Than Death at the end: Being tied to the front of a garbage truck to slowly deteriorate. Easy to play for laughs at the time it happens, but that's before you stop to consider how much time he's liable to be trapped there. Doubles as And I Must Scream - though it's recommended he doesn't, given that bugs and mud would fly into his mouth.
