Primitive War (2025) Review: Vietnam Jungle Meets Prehistoric Predators

This Primitive War review starts with a pitch that sells itself: soldiers in the Vietnam War, a hidden valley, and dinosaurs. Australian filmmaker Luke Sparke writes and directs this action horror hybrid, and he clearly knows the B-movie crowd he is playing to. The result is loud, messy and often entertaining.

Primitive War Review: The Story So Far (No Spoilers)

The Primitive War plot is set in 1968. A recon unit called the Vulture Squad is dispatched to a remote jungle valley to learn what happened to a missing platoon of Green Berets. Ryan Kwanten's Baker leads the way, with a mixed group of soldiers and specialists in tow.

The early stretch builds dread the old-fashioned way. Thick jungle, bad radio signals and nervous soldiers set the mood before anything shows its teeth. It does not take long for the squad to realise the valley hides a threat far older than any war.

The tagline, "This ain't no walk in the park," tells you how seriously the film takes itself. That is a good thing.

What Works in Primitive War

The concept is the big win. Mixing a gritty war film with creature-feature horror gives the movie a clear identity, and it commits to the idea without winking too hard.

The first act is the strongest. Sparke lets tension simmer, and when the dinosaurs finally appear, the reveals are bloody and fun. Audience reactions point to the same thing: viewers enjoy the creature moments, with some calling them more entertaining than several recent big-studio dinosaur films.

A few other strengths stand out:

• Atmosphere: the jungle setting feels claustrophobic and threatening.

• Creature action: the attacks are gory and energetic.

• Period flavour: the soundtrack includes John Fogerty's "Fortunate Son", which fits the era neatly.

For fans of action movie reviews with a horror streak, there is plenty to chew on here.

Primitive War Cast and Performances

The Primitive War cast is led by Ryan Kwanten as Baker, who plays the soldier with a steady, no-nonsense edge. He gives the film a believable centre while the chaos builds around him.

Tricia Helfer plays Sofia, Nick Wechsler is Eli, and Jeremy Piven appears as Colonel Jericho. Anthony Ingruber (Keyes) and Aaron Glenane (Logan) round out the main group. Piven brings a bit of swagger, and the ensemble generally understands the tone: committed, a little over the top, never too self-serious.

Not every character gets room to breathe. Some soldiers are sketched with a single trait, and a few make decisions that viewers will question. That is par for the course in this kind of film.

Where Primitive War Stumbles

At 135 minutes, the movie is long for a monster romp. The pacing sags after the strong opening, and some viewers feel the fun thins out as the story goes on.

The script also leans on familiar war-movie and horror clichés. Dialogue can be clunky, and certain character choices feel built purely to keep the plot moving. Fans of tighter, smarter genre films may find the tone uneven as it swings between grim war drama and goofy creature carnage.

One more caution: the film treats some period attitudes in a blunt way, which may not land for everyone. The low budget occasionally shows too, though the ambition is admirable.

Is Primitive War Worth Watching?

Yes, if you go in wanting a B-movie with real enthusiasm. Primitive War is not a polished masterpiece, but it delivers a bold idea, committed performances and some satisfying dino-horror set pieces.

Its audience score of 6.5 out of 10 on TMDB matches how it plays: uneven but easy to enjoy with the right expectations. The Primitive War release date was 21 August 2025, and it earned a small theatrical gross, so it may feel like a hidden gem for adventurous viewers. If you like horror movie reviews that favour fun over fear, give it a go. For a different kind of survival story, see our take on Phoenix.
