A given with most of, if not all the segments is that their horrifying nature becomes hilarious.
"Q Is For Quack" has the filmmakers propose to kill an actual duck on-camera. Subverted - In the end, they don't.
Zetsumetsu seems to be going for this with a lot of over-the-top sexual imagery, political imagery, and violence, not to mention how confusing it all is.
Ensemble Dark Horse: Most people who've reviewed it, even those who dislike the movie, like X is for XXL because of its combination of social commentary and Body Horror.
How the second film is considered to be by critics.
T is for Toilet's sequel Ghost Burger is much more popular than its predecessor, having nearly double the views and likes than it on YouTube and a higher score on IMDB than the main film itself
Fridge Brilliance: In B is for Bigfoot the Abominable Snow Man is only a danger to children who are out of bed...so, he attacks a woman who had just had sex, and been unknowingly impregnated...
Narm: The ridiculous amount of injury the woman inflicts on her husband in "A is for Apocalypse" and how he's not only somehow alive and conscious afterwards, he doesn't even seem to be in any pain.
XXL is about a woman who decides the best way to lose weight is to carve it all off.
While some may find Z is for Zetsumetsu (Extinction)funny, gross, or just weird and confusing, the darkness, radioactivity warning signs, war imagery, and/or the gratuitous Interplay of Sex and Violence can be pretty scary for some. For some, though, the worst part has to be the title: XXL was about a fat lady, Unearthed was about digging up a vampire, Youngbuck is both about a teenage boy and deer, etc. Whatwent extinctin the film titled "Extinction?"
It should be noted that "zetsumetsu" doesn't just mean extinction: It also means extermination. If that's what they meant, then it makes things even worse via Fridge Horror: At least one side in this war wasn't just trying to stop their enemy: They were trying to wipe them off the face of the earth! And considering that Japan and America (strongly implied to be the other side in this war) have been close allies since the end of World War II in Real Life, what the hell happened for them to turn on each other like that?
Special Effect Failure: The female police officer's gun in "V is for Vagitus" is clearly a Nerf Maverick painted black.
Tear Jerker: The boy's father in "Toilet" watching his son get crushed to death. It's a good thing that the short's sequel Ghost Burger reveals that he survived, with his only injuries being a scar over his now discolored (and capable of seeing ghosts) left eye.
The girl in "XXL" being so desperate to lose weight that she skins herself alive.
What Do You Mean, It's Not for Kids?: Although the movie has a cute cover of a baby reading a book in what appears to be a cool chair, and contains 26 shorts ranging from Wallace & Gromit-style claymation to a live-action short featuring cute Japanese schoolgirls, the title alone should give you a pretty clear clue that it's not for kids, but some people go and show it to their kids anyways. This mindset led to the imprisonment of a high-school substitute teacher.
