Critical response
The review aggregator website Rotten Tomatoes gave the film a rating of 92%, based on 290 reviews, with an average rating of 7.9/10. The site's critical consensus reads, "The Cabin in the Woods is an astonishing meta-feat, capable of being funny, strange, and scary—frequently all at the same time." On Metacritic, the film achieved an average score of 72 out of 100, based on 40 critics, indicating "generally favorable reviews". Audiences polled by CinemaScore gave the film an average grade of "C" on an A+ to F scale.
Roger Ebert of the Chicago Sun-Times gave the film three out of four stars, saying that "The Cabin in the Woods has been constructed almost as a puzzle for horror fans to solve. Which conventions are being toyed with? Which authors and films are being referred to? Is the film itself an act of criticism?" Peter Travers of Rolling Stone gave the film 3.5 out of 4 stars, calling it "fiendishly funny". Travers praised Kristen Connolly and Fran Kranz for their performances, and wrote, "By turning splatter formula on its empty head, Cabin shows you can unleash a fire-breathing horror film without leaving your brain or your heart on the killing floor."
Cinema Blend's Editor in Chief, Katey Rich, gave the film 4.5 out of 5 stars and wrote:
"Even when the story sticks firmly in standard horror territory, this particular group of attractive kids is especially fun to spend time with... You'll have to see it, and you really have to see it if you love horror, hate horror, or have any interest in seeing how the genre can function as a playground for something completely fresh. Richard Jenkins and Bradley Whitford are involved, though in roles that are more fun to discover as you go along-- they do get a lot of the best jokes, though, and their scenes show a lot of Goddard's skill in handling the rhythm of a scene."
Jenkins and Whitford were also admired by The A.V. Club ("Whitford and Jenkins clearly delight in the verbose script") and by Wired, whose reviewer (granting 9 of 10 stars) called Cabin "a smart sendup of horror movies and mythology...with a peculiar relish that testifies to the moviemakers' love of genre film... a smart, sarcastic and deliriously fun journey into the belly of the horror beast." He cited the "witty banter, creative twists" and "clippy, quippy dialog that lifted Firefly and Buffy the Vampire Slayer to cult status."
Ann Hornaday of The Washington Post, giving the movie 3 of 4 stars, wrote:
"A fiendishly clever brand of meta-level genius propels The Cabin in the Woods, a pulpy, deceivingly insightful send-up of horror movies that elicits just as many knowing chuckles as horrified gasps. [It] comes not only to praise the slasher-, zombie- and gore-fests of yore but to critique them, elaborating on their grammatical elements and archetypal figures even while searching for ways to put them to novel use. The danger in such a loftily ironic approach is that everything in the film appears with ready-made quotation marks around it... But by then, the audience will have picked up on the infectiously goofy vibe of an enterprise that, from its first sprightly moments, clearly has no intention of taking itself too seriously."
Eric Goldman, writing for IGN, called the movie "an incredibly clever and fun take on classic horror movie tropes." SF Gate said, "The cliches come at an onslaught pace" in "a wonderfully conceived story that gives a bigger than life and fascinating explanation for why so many horror movie cliches exist in the first place... By the time the ride is over, director Drew Goddard and co-writers Goddard and Joss Whedon will change course three or four times, nodding and winking but never losing momentum." Of the screenplay by Goddard and Whedon, a CNN reviewer praised "these horror hipsters' acidic, postmodern designs on one of the movie industry's hoariest, least respected staples... the dialogue is always a notch or three smarter and snappier than you'd expect."
Keith Phipps of The A.V. Club addressed "...the difficult challenge of putting across a satirical film with a serious body count. Cabin touches on everything from the Evil Dead and Friday the 13th to the mechanized mutilations of the Saw series while digging deeper into the Lovecraftian roots of horror in an attempt to reveal what makes the genre work... It's an exercise in metafiction that, while providing grisly fun, never distances viewers. And it's entertaining, while asking the same question of viewers and characters alike: Why come to a place you knew all along was going to be so dark and dangerous?"
In a more mixed review, Lisa Schwarzbaum of Entertainment Weekly, calling herself "a wised-up viewer", gave the film a "B−" grade and said, "The movie's biggest surprise may be that the story we think we know from modern scary cinema—that horror is a fun, cosmic game, not much else—here turns out to be pretty much the whole enchilada." She nevertheless praised the talents of Whitford and Jenkins: "These two experienced actors provide the film's adult-level entertainment."
Betsy Sharkey of the Los Angeles Times believed that the film "is an inside joke" and also said, "The laughs [in the film] come easily, the screams not so much." David Rooney of The Hollywood Reporter remarked, "It's just too bad the movie is never much more than a hollow exercise in self-reflexive cleverness that's not nearly as ingenious as it seems to think."
A. O. Scott of The New York Times said, "Novelty and genre traditionalism often fight to a draw. Too much overt cleverness has a way of spoiling dumb, reliable thrills. And despite the evident ingenuity and strenuous labor that went into it, The Cabin in the Woods does not quite work." Scott added:
"Some of the pleasure of the first (and best) part of The Cabin in the Woods comes from trying to see just over the narrative horizon and figure out what these incompatible sets of clichés have to do with each other. Two distinct kinds of movie are being yoked, by violence, together, and the performers inhabit their familiar roles with unusual wit."
