To maintain secrecy, actors had to loop dialogue without seeing the accompanying footage. This prevented workers at the audio post-production facility from seeing any critical visual information and leaking it to the press. Series one of "Broadchurch" won near-universal praise. "Radio Times" named it the best television series of 2013, Matthew Bell of the industry journal "Television" called it "a cultural phenomenon", and "Entertainment Weekly" and the "Nottingham Post" called it a "national obsession" in the U.K. A typical critical assessment was made by Tirdad Derekhshani in "The Philadelphia Inquirer": "British TV writer Chris Chibnall achieved something special with the ITV show "Broadchurch": It's a tense, gripping murder mystery, for sure, but the eight-episode series that was shown on BBC America in August also is a brilliantly plotted, multilayered, intimate character study...[f]eaturing a brilliant ensemble cast..." Not all reviews were rhapsodic. Mike Hale in "The New York Times", noted, "It's a pre-eminent example of what could be called the new International Style in television drama: a moody, slow-moving, complicated crime story with damaged heroes and not much redemption to go around." He found the characters "typical", and the show largely redeemed by the superb acting rather than any insightful writing or plotting. Although he praised "Broadchurch's" music, cinematography, and editing, he also pointed out that they were highly derivative of the 2007-2012 Danish murder-mystery "Forbrydelsen" and its 2011-2014 American remake "The Killing". Some reviews were even harsher. John Byrne at RTÉ called "Broadchurch" downright boring. "Broadchurch" series one also received a record-setting number of tweets on Twitter. Series one received a total of 470,000 tweets during its run, the largest number of tweets for an ITV program since Twitter began keeping records. About 260,000 tweets were sent while the final episode aired, with a peak of 8,942 tweets per minute. "Broadchurch" series one was the highest-rated drama on British television in 2013.
