What kind of watch this is
Mike P. Nelson directs this 2026 horror thriller, which runs 104 minutes. The premise involves a medical mission in the Amazon that meets an ancient predator named Boiúna. She wakes up to reclaim her domain, and the humans are just in the way. The tagline promises terror on a gigantic scale, which is a fair warning for anyone who thinks scale alone makes a monster scary. Nature is the final boss here, and she does not take prisoners.
What the critics said
Rotten Tomatoes lands at 58%, with 57 critics averaging 5.6 out of 10. Metacritic sits at 49, indicating mixed or average reception. The consensus notes the film devours chaotic action but lacks genuine thrills. William Bibbiani of The Wrap called it "nasty, mean-spirited nightmare fuel." Rocco T. Thompson of Slant Magazine praised the balance between thrills and thematic bite. Detractors found it slogging and hard to follow. Matt Donato of Daily Dead deemed it underwhelming. The lighting is dim, the pacing rushed, and the geography confusing.
How it did with audiences
On TMDB, users rate it 5.9 out of 10. That is a solid mid-range score, the kind that suggests the film did not break the internet but found a steady audience. Without box office figures to anchor the discussion, the rating stands alone as the primary metric of public reception. It is a decent number, neither a masterpiece nor a disaster, just a movie people watched and rated.
