There are tons of cool sci-fi films to look forward to in the coming weeks. From Flying Lotus psychedelic horror thriller Ash to David Cronenbergs The Shrouds, theres no shortage of exciting new releases to catch in theaters. If youre looking for the best sci-fi movies to watch from the comfort of your own home, though, weve got a couple in mind thatll give the latest slate of films a run for their money and then some.This week, weve picked an indelible sci-fi classic starring Harrison Ford and Sean Young, a critically panned superhero reboot thats actually pretty good, and a maximalist action horror movie with guns and guts galore.Lets take a look at what this month has to offer!Editors pick: Blade Runner: The Final CutDirector: Ridley ScottCast: Harrison Ford, Rutger Hauer, Sean YoungImagine this: Youre in a desert, walking along in the sand, when all of a sudden, you look down and you see a tortoise thats crawling toward you. The tortoise lays on its back, its belly baking in the hot sun, beating its legs trying to turn itself over, but it cant, not without your help, but youre not helping. Why is that?You already know the answer, dont you? Ridley Scotts 1982 neo-noir opus is essentially a litmus (or Voight-Kampff) test for whether or not youll enjoy cyberpunk as a whole, as almost the entirety of the genres tonal, thematic, and aesthetic touchstones are attributable to the films singular vision of a petro-capitalist future teetering on the brink of collapse. It is, in many ways, a perfect sci-fi film, if not a perfect film, full stop. More than four decades since its theatrical release, Blade Runner remains a timeless and essential work of art. Toussaint EganPower RangersDirector: Dean IsraeliteCast: Dacre Montgomery, Naomi Scott, RJ CylerNo matter who you ask, just about anyone will tell you that making a Power Rangers reboot movie in 2017 seemed like a terrible idea. And yet, director Dean Israelite pulled off one of the most fun, interesting, and inventive blockbusters of the 2010s.The plot of the movie is mostly a copy of the original shows first episode. A group of five kids find magical coins that grant them incredible powers and the ability to transform into colorful-suited Power Rangers and talk to Zordon, a floating hologram head voiced by Bryan Cranston. At the same time that they gain this power, the evil Rita Repulsa, played by Elizabeth Banks in a ridiculously fun performance, awakens from her 65 million-year slumber with a new plan to take over the world that only the Power Rangers can stop.The fact that all this works is due in large part to the movies excellent cast, which includes a few stars, like Banks and Cranston, and several young actors who were about to break out, like Dacre Montgomery, Naomi Scott, and RJ Cyler. On top of that, the movie is smart enough to play everything straight, rather than being ashamed of its source material or overly nostalgic. Austen GoslinResident Evil: RetributionDirector: Paul W.S. AndersonCast: Milla Jovovich, Michelle Rodriguez, Kevin DurandPaul W.S. Anderson is back in theaters with his new movie In the Lost Lands, which means its a perfect time to revisit one of the best entries in his excellent Resident Evil franchise. Resident Evil: Retribution is the fifth movie in the series, the third directed by Anderson, and it feels like the first time in the series he was given the space to go all out with his action.Alice (Milla Jovovich) has been captured by the evil Umbrella Corporation and is being held inside its top-secret base somewhere in Russia. The base itself has dozens of massive rooms, each designed to simulate some of the biggest cities in the world, like New York, Tokyo, and Moscow. This provides Retribution with the perfect excuse to stage some extremely cool action set-pieces in each of these locations, with thousands of teeming zombies attacking Alice and her allies.This premise makes Retribution a surprisingly strong jumping-on point for the series, and turns the whole movie into a fantastic sci-fi action romp.
