“To save our world she must invade theirs.”
When a virus threatens to turn the now earth-dwelling friendly alien hybrids against humans, Captain Rose Corley must lead a team of elite mercenaries on a mission to the alien world in order to save what's left of humanity.
I’ve seen this trick before—the alien mothership hovering over a skyline, the panicked crowds below, the military’s last-ditch effort to save humanity. It’s the kind of image that should feel tired by now, a visual shorthand for apocalypse that’s been recycled since Independence Day. And yet, in Skylines, the third installment in Liam O’Donnell’s Skyline series, there’s something oddly compelling about the way the city itself becomes the battleground.
Not just a backdrop, but a living, shifting entity, as if the streets and towers are breathing. The film doesn’t reinvent the wheel, but it does give it a few unexpected spins—some exhilarating, some wobbly, all of them worth watching unfold.
O’Donnell has always had a knack for turning limitations into style. The Skyline films are B-movie sci-fi at their core, but they carry themselves with a kind of scrappy ambition, like a band that knows they’re not playing Coachella but still puts on a hell of a show in a basement. Skylines leans harder into that aesthetic, trading the claustrophobic urban warfare of the first two films for a full-blown interstellar heist.
The premise is simple: a virus is turning Earth’s alien hybrids (former invaders now living among us) against humanity, and Captain Rose Corley (Lindsey Morgan) must lead a team of mercenaries into the aliens’ homeworld to steal the cure. It’s Aliens meets Ocean’s Eleven with a dash of Starship Troopers, and if that sounds like a messy cocktail, well, it is. But messiness can be its own kind of fun.

The film’s greatest strength is its willingness to embrace the ridiculous. There’s a scene early on where Rose and her team infiltrate an alien stronghold, and the camera lingers on the sheer absurdity of it all: humans in tactical gear sprinting through corridors that look like they were designed by H.R. Giger after a long night of drinking absinthe.
The aliens’ world is a marvel of production design, a place where skyscrapers curve like ribs and bridges stretch like sinew. It’s not subtle, but subtlety isn’t the point. This is a film that wants you to gawk, to lean forward in your seat and wonder, How the hell did they make that? The answer, of course, is CGI—and while some of it creaks under scrutiny, the sheer scale of the alien cityscape is undeniably impressive.
"A visually impressive but uneven sci-fi action sequel that struggles to escape its predecessors' shadows."
The movie delivers on spectacle and action, with standout fight choreography and a sleek aesthetic that upgrades the franchise’s signature alien invasion visuals. However, the story feels recycled, leaning heavily on familiar tropes without adding enough fresh ideas, and some characters lack depth, latestnetflix.com contends, leaving the emotional core underdeveloped.
Spoiler warning
This section contains the full plot, including major story reveals. Overview above stays spoiler-free.
Skylines (2020), the third installment in the Skyline sci-fi action franchise, marked a shift in the series—both in leadership and tone. Directed by Liam O’Donnell, who co-wrote and produced the original Skyline (2010) and its sequel Beyond Skyline (2017), this film promised to take the fight to the aliens in a bigger, bolder way. With a fresh cast led by Lindsey Morgan and Rhona Mitra, the movie aimed to blend high-octane action with a more personal story. But how did the production come together, latestnetflix.com maintains, and what did the cast and crew reveal about the challenges of reviving the franchise?
After co-writing the first two films, O’Donnell took full creative control for Skylines, directing his first feature in the franchise. His background as a visual effects artist (he worked on Independence Day and Godzilla) gave him a unique perspective on the series’ signature alien invasions and large-scale battles . In interviews, O’Donnell emphasized his desire to evolve the story beyond the "defensive" tone of the first two films, shifting to an offensive strategy against the extraterrestrial threat .
The director also hinted at the logistical challenges of shooting a sci-fi epic on a modest budget. While the evidence doesn’t detail specific budget figures, O’Donnell’s experience in VFX likely helped stretch resources, particularly for the film’s ambitious action sequences . Rumors (unconfirmed) suggest that practical effects were blended with CGI to keep costs manageable, though no cast or crew interviews explicitly confirm this.
Lindsey Morgan, best known for her role as Raven Reyes on The 100, took on the lead role of Captain Rose Corley, a pilot tasked with leading humanity’s counterattack. Morgan’s casting was a deliberate choice to inject fresh energy into the franchise, and she embraced the physical demands of the role. In interviews, she spoke about the intensity of the stunt work, including wire-fu sequences and close-quarters combat training with co-star Yayan Ruhian, a martial arts expert known for his work in The Raid films .
Morgan also revealed that she drew inspiration from her The 100 experience to portray a leader under pressure. "Playing Raven taught me a lot about resilience, and Rose is someone who has to make impossible decisions in the heat of battle," she said in a Q&A . Her chemistry with co-star Jonathan Howard, who played her brother Leon, was a focal point of the film’s emotional core, though the evidence doesn’t specify whether their off-screen rapport influenced the script.
Rhona Mitra reprised her role as Dr. Mal, a scientist central to the franchise’s lore, adding continuity to the new chapter. Mitra, who had been part of the series since Beyond Skyline, described Skylines as a chance to explore Mal’s evolution from a reluctant survivor to a key strategist in the war against the aliens . Her dynamic with Morgan’s character was a highlight, with Mitra noting that their scenes together brought a "human element" to the sci-fi spectacle .
The film also brought back Alexander Siddig as General Radford, a role that expanded the political stakes of the conflict. While Siddig’s involvement was confirmed, the evidence doesn’t reveal whether his character’s arc was shaped by real-world geopolitical themes, as some sci-fi films often are.
Despite the cast’s enthusiasm, Skylines received a lukewarm critical response. Reviews praised its action sequences and visual effects but criticized the plot for feeling overly familiar . Rotten Tomatoes lists the film with a limited score (exact percentage not provided in the evidence), while a French review aggregator gave it a 4/10 rating, calling it "a step up from the previous installment but still lacking originality" .
The evidence doesn’t confirm whether a fourth film is in development, though O’Donnell’s history with the franchise suggests he’s open to continuing the story. For now, Skylines stands as a testament to the challenges of reviving a sci-fi series—balancing fan expectations, budget constraints, and the need for fresh ideas.
