From "USA Today" review (no spoilers):
Arrival, easily the best film of 2016, only seemed to be director Denis Villeneuves signature sci-fi project. Blade Runner 2049, the best film so far this year, cements him as a bona fide icon of the genre.
...the new Blade Runner amazes because every aspect is top notch: Hampton Fanchers story is surprisingly emotional, Benjamin Wallfisch and Han Zimmers pounding soundtrack is just as integral as Vangelis ethereal original score, and cinematographer Roger Deakins will get his first Oscar if theres any justice. The sequel takes the futuristic action out of L.A., ...and the stunning visuals add to the enjoyably visceral experience.
The first Blade Runner influenced a generation of filmmakers and films; 2049 is the rare sequel that exceeds the original and honestly could be more important in the long run. Its a moving, masterful movie that demands a rewatch and will wow geeks and mainstream viewers alike so much so we probably wont have to wait 35 years for another one.
