Kathleen Murphy, MSN Movies: Builds legitimate haunted-house dread ... [but] at a very specific point ... possession turns jokey and hokey. Read more
Mike Hale, New York Times: The strongest analogue for the second half of "Insidious" is one that the filmmakers probably weren't trying for: it feels like a less poetic version of an M. Night Shyamalan fairy tale. Read more
Christy Lemire, Associated Press: Insidious is the kind of movie you could watch with your eyes closed and still feel engrossed by it. Read more
Joshua Rothkopf, Time Out: The film's low-budget atmospherics and cliched floor-creakings are a poor substitute for Wan's nauseating impact of yore. Read more
David Edelstein, New York Magazine/Vulture: The thing is scary as hell when it's all creaks and thumps and doors swinging open. Then come the explanations, the special effects, and the inevitable feeling of been-there-been-bombarded-by-that. Read more
John Anderson, Wall Street Journal: "Insidious" establishes that these folks can make a film that operates on an entirely different level, sans gore, or obvious gimmicks. And make flesh crawl. Read more
Scott Tobias, AV Club: All calculation aside, scary is still scary, and Insidious makes up in old-fashioned tension what it sometimes lacks in originality. Read more
Bill Goodykoontz, Arizona Republic: No blood, no gore, no hacked-off arms and legs, but plenty of creepy set pieces, quick cuts and blasts of music that will have you both squirming in your seat and jumping out of it. Read more
Ethan Gilsdorf, Boston Globe: The final shocker succeeds in shocking, and does so sans gore. But first we have to wade through a red door and a red hallway, pleas to "follow my voice,'' and an infinity of fog about as scary as dry ice vapor spilling onto a dance floor. Read more
Ben Sachs, Chicago Reader: Aesthetically, Insidious operates at the level of a decent high school video project. Read more
Michael Phillips, Chicago Tribune: Director James Wan and screenwriter Leigh Whannell admire all sorts of fright, from the blatant to the insidiously subtle. This one lies at an effective halfway point between those extremes. Read more
Tom Long, Detroit News: Insidious isn't scary. It's laughable. And kind of sad. Read more
Owen Gleiberman, Entertainment Weekly: Insidious is a haunted-house movie that has some of the most shivery and indelible images I've seen in any horror film in decades. Read more
Eric D. Snider, Film.com: Whatever flaws it may have, Insidious scared the hell out of me. Read more
John DeFore, Hollywood Reporter: A surprising number of these gotcha moments have the desired effect, and the picture's first hour strings them along through a familiar tale. Read more
Connie Ogle, Miami Herald: The film is stylish and quietly unsettling even in its derivativeness, and it delivers the sort of slow-building chills that ruffle the hair at the back of your neck, at least until the frights get a little too literal, in the movie's third act. Read more
Bruce Diones, New Yorker: Wan and Whannell have, in effect, ripped pages from the "Poltergeist" playbook and stripped the formulas down to old-style gothic scares. Read more
Stephen Whitty, Newark Star-Ledger: There's little new here. And what is new isn't well done. Read more
Steven Rea, Philadelphia Inquirer: If your idea of a fun night out is to be manipulated by freaky sound effects, jumpy edits, and point-of-view shots of ceiling fans whooshing menacingly, Insidious is the film for you. Read more
James Berardinelli, ReelViews: If there's a complaint to be made about Insidious, it's that the film's second half is unable to live up to the impossibly high standards set by the first half. Read more
Roger Ebert, Chicago Sun-Times: Not terrifically good, but moviegoers will get what they're expecting. Read more
Peter Travers, Rolling Stone: Here's a better-than-average spook house movie, mostly because Insidious decides it can haunt an audience without spraying it with blood. Read more
Andrew O'Hehir, Salon.com: It turns out to be a moderately effective suburban-family creep show, majorly in debt to "Poltergeist" and "The Exorcist" and capturing at least a little of their spirit. Read more
Mick LaSalle, San Francisco Chronicle: From the opening credits, in which the title appears in blood-red letters to the accompaniment of blaring, dissonant music, the movie tries to get under your skin and inside your mind. Sometimes it does. Read more
Colin Covert, Minneapolis Star Tribune: The film is weighed down by too many forehead-palming lapses and an overall sense of "been there." Read more
Liam Lacey, Globe and Mail: Nothing slows down a movie down like people sitting around a living room discussing the meaning of "astral projection." Read more
Claudia Puig, USA Today: There's not much that's insidious, or subtle, here. A prolonged scene involving an unnerving high-pitched burglar alarm does get under our skin. But it's far more annoying than frightening. Read more
Nick Pinkerton, Village Voice: It doesn't build a better haunted house but, when on its game, reminds us of the genre's pleasures. Read more
Michael O'Sullivan, Washington Post: It's too much "Saw" and not enough "Paranormal." Read more
