Skyline (2010) presents a chilling sci-fi scenario where mysterious blue lights descend upon Los Angeles, hypnotically drawing residents toward an otherworldly threat. Directed by the Brothers Strause, this alien invasion thriller follows a group of friends who become trapped in a luxury high-rise as extraterrestrial forces begin harvesting humanity. The film effectively builds tension through its initial mystery, with the characters' confusion mirroring the audience's own as the scale of the invasion becomes terrifyingly clear.

The visual effects, particularly for its modest budget, deliver impressive alien designs and destruction sequences that create genuine moments of spectacle. Eric Balfour and Scottie Thompson anchor the human drama as a couple facing both relationship tensions and existential terror, while Donald Faison provides solid support as their friend. The film's strongest element is its relentless pace—once the invasion begins, the action rarely lets up across its tight 92-minute runtime.

While Skyline received mixed reviews for its familiar invasion tropes and character development, it succeeds as an efficient B-movie thriller with striking visuals. The film's practical approach to depicting an apocalyptic event from a single location perspective creates claustrophobic intensity. For viewers seeking undemanding sci-fi action with impressive creature designs and non-stop alien encounters, Skyline delivers solid entertainment value when watched online for its visual spectacle alone.
