The first thing I thought of when I read the title was those Youtube videos that seem to exist solely to trash on movies, books, games, celebrities, or whatever. The "entertainment" there is supposed to be the Youtuber pointing out the flaws with whatever subject they're focussing on, then making a big stink about it.
CinemaSins comes to mind. Putting aside the fact that sometimes their "sins" make no sense, their videos have just been getting longer and longer and longer - from "Everything wrong with movie X in 3 minutes" to "Everything wrong with yada-yada-yada in 19 minutes." You can't make 19 minutes of criticism, in their motor-mouth jump-cut style, without just plain making up some gripes for the sake of griping. Even Yahtzee only goes for five minutes or so, and he's usually telling actual jokes that are funny to hear.
There was also this video my friend showed me, from like a vegan channel or something, but the video was just the Youtuber talking about how great it was that this other Youtuber he had a spat with had just found out he had cancer, and that it was his own fault for not being a vegan.
Oh, here it is. [https://www.youtube.com/watch?v=Okd3vFUwqj4] Seriously, I can't watch more than thirty seconds of that video. It should be illegal to be that much of a douche.
Stuff that isn't Youtube being terrible...torture porn, even when played for satire. A Serbian Film is a great example. A friend of mine kept bugging me to watch it with him and when we finally did I walked out thirty minutes in and barely stopped myself from punching him in the face. I was genuinely angry that he thought I'd like the film, even on an ironic level. The Human Centipede films would also count if I'd ever actually watched ny of them.
But what really gets me is Crossed. For those of you who don't follow comics, it's a series initially created by Garth Ennis that posits a zombie-apocalypse style scenario, except the zombies aren't dead - the virus turns them into violent sadists, like 28 Days Later but they're still intelligent. The "draw" of the series is that it was published by Avatar, so it was completely uncensored, and the artists went crazy on the gore-porn. Like...ugh. If you have a strong stomach, google some of the covers. I won't link any here, they're too NSFW.
Basically, imagine a zombie apocalypse except instead of eating you, the zombies want to torture, rape, and skin you in the most intentionally cruel way possible, and then do horrible things with your body and the bodies of your family. These are zombies who intentionally gang-rape victims in order to convert them the way regular zombies would just bite you. Often, they're what tvtropes call "villain sues" - inexplicably competent villains that thwart all efforts by the heroes to defeat them. It doesn't matter how many guns you have, how organised you are, or how medically impossible it is for guys like the Crossed to even survive through one winter; if you're reading a Crossed story, at the end of it, ninety percent of the cast will be dead and the survivors will either be assholes, or they'll be Crossed. Sometimes, they'll eat their own baby. Literally. Like, roasting it on a spit.
The whole title, regarldess of who's writing (it's a multi-author thing these days) is almost hypnotically disgusting. It's an exercise in pushing the imaginative limits of human cruelty. I do go back to it from time to time, when I think it's doing something interesting - there are only so many ways you can torture-rape-murder someone before it gets boring - but even when it's doing something new-ish, like Moore's Crossed 100, it still manages to be so thoroughly hopeless and cruel that I just can't finish it.
