Critical quotes:
"This film is so bad that I feel compelled to make a spoiler-laden list of its most laughably terrible parts rather than review it. M. Night Shyamalan's latest movie, The Happening, is not merely bad. It is an astonishment, so idiotic in conception and inept in execution that, after seeing it, one almost wonders whether it was real or imagined." - Christopher Orr, The New Republic, 2008
"If Shyamalan wanted to commit career suicide he couldnt have chosen a more likely vehicle than this laugh inducing 'thriller.'" - Richard Knight, Jr., Windy City Times
"...more scary than silly."- Efilmcritic, 2008
"A disaster, representing a number of negative firsts for Shyamalan."- Ryan Stewart, 2008
"You feel like you're not watching the end of the world but the end of a career."- Boston Globe, 2008
"Being risibly bad, The Happening is at least worth a laugh."- Rick Groen
"A movie that I find oddly touching. It is no doubt too thoughtful for the summer action season, but I appreciate the quietly realistic way Shyamalan finds to tell a story about the possible death of man."- Roger Ebert, 2008
"In short, this is a Shyamalan movie minus the bravado"- Justin Chang, 2008
"It's an entertaining movie"- Mick La Salle, 2008
"The Happening is a movie to walk out of, sleep through, or - best of all - not to bother with. "-James Berardinelli, 2008
"A disappointingly slight offering from a filmmaker that we know is capable of so much more. Shyamalan says that The Happening was his easiest film to shoot. Sadly, it shows."- Empire Magazine, 2008
"If what audiences are looking for is a thrill ride, or even a pervasive eeriness, The Happening's just not happening."- NPR, 2008
"An unapologetic B-movie. "- William Arnold, 2008
"...divertingly goofy thriller with an animistic bent, moments of shivery and twitchy suspense and a solid lead performance from Mark Wahlberg"- The New York Times, 2008
"Wahlberg turns in one of his worst performances ever"- Chicago Reader, 2008
"The Happening makes you wonder whether Mr. Shyamalan's own switch may have been flipped. How else to explain his film's befuddling infelicities, insistent banalities, shambling pace and pervasive ineptitude? "- Wall Street Journal, 2008
