The New York Times says,
There is a something to think about here, a fair amount to feel and even more to see. Mr. Villeneuve has conspired with the cinematographer, Roger A. Deakins; the production designer, Dennis Gassner; and the special effects team to create zones of strangeness that occasionally rise to the level of sublimity.The Washington Post says it "honors -and surpasses— the original". The Guardian gives it 5 out of 5 stars. Empire Online gives it 5 out of 5 stars and concludes, "Visually immaculate, swirling with themes as heart-rending as they are mind-twisting, 2049 is, without doubt, a good year. And one of 2017’s best."
Roger Ebert's site gives it 3.5 out of 4 stars and says,
while hundreds of writers and filmmakers were inspired by “Blade Runner,” it’s hard to believe any of them could have found a way to expand its legacy as completely as Villenueve does here with a movie that doesn't feel at all repetitive. He’s in no way seeking to improve or replace—the films now work together, enriching each other instead of mimicking. They ask timeless questions and, like all great films, refuse to give you all the answers, allowing viewers to debate and discuss their meaning instead of merely being passive recipients of mindless entertainment.Rotten Tomatoes has a critics score of 88%.
