Critical response
Following the Los Angeles premiere, Metro noted that early critical reaction was "glowing", with critics describing it as a "spectacle", while The Guardian reported that it was receiving "much stronger early reviews". However, before the film's theatrical release, E! reported that reviews had been "mixed", but stated they were still "much better" than the previous film. After the film's international release, MTV reported that the film has garnered a "positive" critical reaction, while the Los Angeles Times stated the consensus is that the film "reinvigorates" the series, putting it "back on course". On review aggregator Rotten Tomatoes the film has 74% approval rating with an average rating of 6.80/10 based on 251 reviews from professional critics. The website's consensus reads, "While still slightly hamstrung by "middle chapter" narrative problems and its formidable length, The Desolation of Smaug represents a more confident, exciting second chapter for the Hobbit series. On Metacritic, the film has a score of 66 out of 100 based on 44 reviews, indicating "generally favorable" reviews. Audiences polled by CinemaScore, during the opening weekend, gave it an average grade of "A−" on a scale from A+ to F, down from the first film which scored an "A" grade.
Nick de Semlyen of Empire awarded the film five stars out of five and wrote that "Middle-earth's got its mojo back. A huge improvement on the previous instalment, this takes our adventurers into uncharted territory and delivers spectacle by the ton", while Richard Corliss of TIME declared it one of the top ten films of 2013, and wrote "In all, this is a splendid achievement, close to the grandeur of Jackson's Lord of the Rings films." Justin Chang of Variety wrote that "After a bumpy beginning with An Unexpected Journey, Peter Jackson's 'Hobbit' trilogy finds its footing in this much more exciting and purposeful second chapter." Todd McCarthy of Hollywood Reporter wrote that "Nearly everything... represents an improvement over the first instalment of Peter Jackson's three-part adaptation of J.R.R. Tolkien's beloved creation." He also praised the High Frame Rate of The Desolation of Smaug as being better than that of An Unexpected Journey. Mark Hughes, who reviewed the film for Forbes, was highly enthusiastic, and felt "The Desolation of Smaug is another grand entry in the Tolkien saga, raising the emotional and physical stakes while revealing more of the sinister forces," before concluding "It's pleasing to see a filmmaker this in love with storytelling, this committed to creating entire worlds... that's a rare thing indeed, and for it to turn out so well is even more rare. It's a sight to behold, and you won't be sorry you did."
Peter Bradshaw of The Guardian scored the film four stars out of five, writing, "It's mysterious and strange, and yet Jackson also effortlessly conjures up that genial quality that distinguishes 'The Hobbit' from the more solemn 'Rings' stories." Total Film also scored the film four stars out of five, but reviewer Matt Maytum noted that, in his opinion, the film suffered "from middle-act wobbles." Despite this, he praised the "rousing action... incredible visuals... and one stupendous dragon", and concluded his review saying "There's a lot to admire in The Desolation of Smaug." Jim Vejvoda, who reviewed the film for IGN, awarded it 8.5 out of 10, and felt "It's a breathlessly told, action-packed crowd-pleaser that restores the luster of the saga for those underwhelmed by its predecessor and leaves you excited for the final chapter in the trilogy."
Conversely, Peter Travers, who reviewed the film for Rolling Stone, gave it two and a half stars out of four. He felt it was "a little less long and a little less boring" than the first instalment, and offered praise for the depiction of Smaug, saying "as a digital creation, Smaug is a bloody wonder of slithering fright." He was, however, very critical of the film's padding of a "slender novel", but concluded: "I'd endure another slog through Middle-Earth just to spend more time with Smaug". Robbie Collin of The Daily Telegraph was even less admiring, and awarded it two stars out of five. He too criticised the decision to turn Tolkien's book into three films and felt Jackson "is mostly stalling for time: two or three truly great sequences tangled up in long beards and longer pit-stops." He continued, writing "There is an awful lot of Desolation to wade through before we arrive, weary and panting, on Smaug's rocky porch," and disapproved of the introduction of a love triangle to Tolkien's narrative, adding: "Maybe this really is what a lot of people want to see from a film version of The Hobbit, but let's at least accept that Tolkien would probably not have been among them."
