We take no joy in trashing the work of others, which is why even though our list of The Best Movies of 2013 is 25 films deep, and the list below is only 10.
Still, some movies leave such a bad aftertaste that crafting a list of the year's biggest stinkers felt like a professional responsibility.
From unfunny comedy to laughable sci-fi to depressing, franchise-tainting action, here are the movies we enjoyed the very least this year.
10. "The Hangover Part III"
The third (and thankfully final) installment in director Todd Phillips's lucrative franchise played more like a dark, humorless action film than a compelling, guys-gone-wild comedy. Stale characters, lack of a narrative, and an excessive amount of animal cruelty jokes made many realize that the Wolfpack should have been euthanized after the first, unnecessary sequel. —Matt Whitfield
Whatever new and unique ideas Spike Lee and Josh Brolin attempted to bring to their "reinterpretation" of Park Chan-wook's 2003 film were quite literally lost in translation. With or without spoiling the film's oh-no-they-didn't twist, Chan-wook's original explores the twisted, dark depths of human nature and survival instincts in a compelling, artistic fashion; Lee's version hits the exact same notes but in an oddly paced, flat and off-putting fashion. —Kara Warner
8. "Grown Ups 2"
Adam Sandler stars in yet another a goofball, lowbrow, bro-tastic comedy … and it's a sequel! Just because fish-out-of-suburbs "Grown Ups 2" made decent dough, raking in $246 million worldwide, doesn't mean it'sgood. Critics panned the heck out of it for its predictable raunch and overall laziness. We just think bringing the guys together again in their hometown — heck, in any setting — is a horrendous idea. —Meriah Doty
7. "The Canyons"
No one expected the movie funded through Kickstarter starring Lindsay Lohan and James Deen to be good, necessarily. But we didn't figure it would be quite so, well, boring. Bret Easton Ellis's script was plodding, and Paul Schrader's direction was plodding. Lohan and Deen didn't embarrass themselves, though the rest of the supporting cast pretty much did. But this was the sort of film that could have been either a surprisingly engaging gem or a laughably awful midnight movie, and it was neither. Instead of being "so bad it's good," it landed square in the middle of bad and didn't go any farther. —Matt McDaniel
6. "Machete Kills"
You can almost see the wires the witches are hanging from when they "fly" to rustle up trouble with Hansel and Gretel. (Jeremy Renner and Gemma Arterton, what were you thinking!?) It reads like a studio exec's "hurry-up-and-capitalize-on-fairy-tales-trend" gone terribly awry, with awful stunts and cheesy effects. Rivaling the horridness of one of film's worst movies "The Room," "Hansel & Gretel: Witch Hunters" is watchable in the vein that it's so tremendously bad it's good. —Meriah Doty
4. "The Lone Ranger"
You call this "The Lone Ranger"?! More like The Lame Ranger! (Zing!) Johnny Depp and director Gore Verbinski tried fruitlessly to recreate the thrill-ride magic they had on the first "Pirates of the Caribbean" movie set in the classic Western backdrop. Furthermore, Captain Jack Sparrow as the beloved Tonto not only didn't work, but it was in questionable taste. Even the energetic classic "Lone Ranger" theme music (otherwise known as Rossini's "William Tell Overture") wasn't exciting enough to get this train to leave the station. —Breanne L. Heldman
3. "After Earth"
With a seemingly interesting premise and one of our favorite actors, this Smith family affair showed a lot of promise. Unfortunately it also showed Jaden trying to be an action hero, the flattest performance Will has ever delivered, and a disheartening lack of heart. If you're going to put a giant video game up on screen — and a sterile, boring one at that — at least give us a joystick to play along and try to veer the story away from the completely predictable. —Adam Pockross
2. "Movie 43"
1. "A Good Day to Die Hard"
It's bad enough this bloated behemoth blew up Budapest (Moscow's stunt double) in lieu of a script (when did John McClane become a spy exactly?), but to sully the good name of one of action's most beloved franchises is just too much to ignore. And while even McClane on his best day couldn't save this mailed-it-in stinker, at least Bruce Willis could have tried.
