Jurassic Park brought dinosaurs to the mainstream and revolutionized the sci-fi monster subgenre. For years, there hasn't been another franchise or movie that comes anywhere near to being a worthy replacement candidate. However, this could change with the release of the new dinosaur flick, directed by Luke Sparke. The 2025 Australian movie, Primitive War, is similarly based on a sci-fi novel. Taking place during the Vietnam War, the movie follows the Vulture Squad, led by Sergeant Ryan Baker, as they enter a dinosaur-infested valley during a mission.

Facing threats from both their enemies and ancient creatures, the Vulture Squad has to rely on itself for survival. The underrated sci-fi flick has divided critics since its world premiere. While the critics can't agree on how they feel about the new movie, the fans are loving it. Currently playing in limited theaters, the R-rated movie gives every dinosaur movie enthusiast something they have been craving since Steven Spielberg's 1993 classic.
Primitive War Is Much More Gory Than Jurassic Park

The Jurassic Park franchise has maintained its PG-13 rating since the 1993 movie that kick-started the world's fascination with dinosaur movies. While the rating has made the franchise more accessible for a larger audience group, as a franchise that builds on the premise of a sci-fi disaster, not having an R-rated horror movie becomes the one thing it missed out on. The franchise's gripping plotlines and the actors' top-notch performances made up for the lack of gore and violence, and for the longest time, it almost seemed like there was no need for an R-rated dinosaur movie. However, Primitive War puts that into perspective, proving that an R-rated dinosaur horror movie is exactly what the franchise lacked. The 2025 horror flick delivers a version of the dinosaur movie that fans didn't know they needed. Primitive War is filled with explicit death scenes and gory details that Jurassic Park never delivered. Since its release, fans have crowned the movie as the most horrific dinosaur movie they've ever seen.
Adapted from Ethan Pettus' novel of the same name, the movie stays faithful to some of the most brutal scenes described in the book, including one scene where a Quetzalcoatlus (widely believed to be the largest flying reptile ever to exist on Earth) flies down and starts feeding on a soldier's intestines while he's still alive. The terrifying scene was already jaw-dropping enough, but it's hardly the worst. Primitive War takes a bit of time in the first 20 minutes to warm up the audience to the horror that lies in the dinosaur-infected valley. After a few harmless hide-and-seeks with seemingly threatening species, the level of danger rises rapidly the closer the Vulture Squad gets toward the collider. Gerald Keyes' death is arguably the most difficult to watch. Having been dragged away by Utahraptor and speared in the stomach while being silenced, he escaped death in the attack but couldn't escape his ultimate fate. By the time Primitive War wrapped, there were few left alive in the Vulture Squad. Discussing a team of soldiers being sent into an impossible war zone to fight not only human enemies but also extinct species accidentally brought back, Primitive War delivered a thrilling viewing experience that blends gruesome deaths with humor and heart. Jurassic Park is an all-time classic, but the franchise has been playing it safe. Luke Sparke's 2025 dino horror flick is a rare project that blows everything wide open.
