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 Hangover III More

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 stocked. Stale characters, lacking 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

9. "Oldboy"

Oldboy More

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"

Grown Ups 2 More



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's good. 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"

The Canyons More



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' 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
