Beware Boiúna hit theaters on October 2, 2026, after premiering at Fantastic Fest. Directed by Mike P. Nelson, known for previous horror work, the film stars Jessica Rothe, Kiana Madeira, and Logan Marshall-Green. It belongs to the giant-animal attack subgenre and draws from Brazilian Amazon folklore about a powerful serpent. Early audience response has been mixed.
Some viewers called it one of the stronger recent snake movies and praised the suspense, while others felt it took too long to deliver the creature they came to see. The story follows a small medical team on a humanitarian trip deep in the Amazon rainforest. Their boat journey and efforts to help local communities quickly become complicated by conflicts with other people in the area.
The group’s presence and the resulting chaos awaken Boiúna, an ancient and massive serpent that views the intrusion as a threat to its domain. What begins as a medical mission turns into a fight for survival against both human threats and the creature itself. On X and in early online discussions, many people highlighted the strong work from Jessica Rothe and Kiana Madeira, noting their committed and believable performances under pressure.
Viewers frequently praised the intense attack scenes and the sense of danger once the snake becomes active, with some saying the creature looks impressive when fully shown and that the film feels meaner and more serious than typical entries in the genre. A number of posts compared it favorably to older titles like Anaconda and called the theater experience loud and effective.
Common complaints focused on the slow first half. Several audience members said the movie spends too much time setting up characters and conflicts before the main threat takes over, making the runtime feel longer than necessary. Others noted that the snake appears less often than expected early on, and a few found the ending less satisfying or the overall tone too serious for a creature feature.
Some described it as feeling low-budget in places despite the Lionsgate distribution. Fans of survival horror and giant-animal movies who enjoy atmospheric tension and solid acting will likely get the most out of it. The jungle setting and folklore angle give it a distinct flavor compared with more campy entries.
Its main weaknesses are the drawn-out opening and limited creature screen time in the early going, which can test patience. For those who like this style of film, seeing it in theaters makes sense because the sound design and scale of the attacks benefit from a big screen and loud speakers. Others may prefer waiting for streaming if they are sensitive to slower pacing or prefer more consistent monster action from the start.
