Critics, per Wikipedia

On the review aggregator website Rotten Tomatoes, 58% of 60 critics' reviews are positive, with an average rating of 5.6/10. The website's consensus reads: "Devouring too much chaotic action and not enough genuine thrills, Beware Boiúna fails to make the most of its mythical monstrosity despite some creative narrative twists." On Metacritic, which utilizes a weighted average, assigned the film a score of 49 out of 100, based on 8 reviews, indicating "mixed or average" reviews. William Bibbiani, writing for The Wrap, called the film "nasty, mean-spirited nightmare fuel" and highlighted Nelson's direction. For Slant Magazine, critic Rocco T. Thompson praised Junkersfeld's photography of the…

    Beware Boiúna: rickety-bridges-and-quicksand cinema is alive and well in 2026. Very sturdy, grisly movie indulging in fine tried-and-true traditions. One of the better horror films I've seen from this year.

    Be mindful of quicksand and stay out of the Amazon because we are discussing Mike P. Nelson's creature feature, Beware Boiúna (2026). It's the first theatrical snake film in <forever> so we're psyched, but this is just...fine? Perhaps it’s because this film borrows heavily from the OG ANACONDA?

    Beware Boiúna made $550,000 at the box office this weekend on more than 1,100 screen. So under $500 per theater. Anaconda from last year was a letdown and may have poisoned the giant snake waters but I think "Beware Boiúna" is also a terrible name for a horror movie cuz no one knows what it means.

    Better than it has any right to be, Beware Boiúna is a killer titanoboa movie that sinks its teeth perfectly into its premise. Madeira and Rothe are stellar and the creature effects are incredible! Wish it had more meat to the story and wasn’t so dark though. www.horror2themax.com/articles/gia...

  • Chris Sawin @ChrisSawinTMDB reviews · Oct 11, 2026

    Beware Boiúna is very much about getting this group of people into the rainforest for a vague reason and then dropping its story points purely for a bloody snake massacre. It is chock-full of jerky camera movements jittering to an obnoxiously loud sound mix. Repetitive loud noises in a film basically equate to elongated jump scares. Beware Boiúna isn't stingy when it comes to butchering people in countless slimy and slithery ways, but it's all something that could have been avoided if they…

  • 💌 SpookyMaevey 🏳️‍⚧️ @spookymaevey.bsky.socialBluesky · Oct 8, 2026

    Beware Boiúna feels very timely considering the election of Bolsanaro in Brazil. It's a movie that's like if Anaconda was a pretty good movie rather than a pretty silly movie, and has the ultimate message that we must protect the Amazon (and all old growth forests really)

  • Leninhawk @leninhawk.bsky.socialBluesky · Oct 7, 2026

    #BewareBoiúna - An okay giant snake movie with too much shaky cam that doesn't fully embrace the concept of a theatrical, R-rated giant snake movie. The VFX are decent enough. Also wished the human antagonists were more evil throughout. My review: letterboxd.com/leninhawk/fi...

    Beware Boiúna: I really enjoyed this a lot more than I expected. Very well made and feels like a grindhouse film from the 1970’s. The snake is used very minimally to great effect so that it is a lot more terrifying. The plot also goes in many unexpected directions too.
