A medical student, Alli (Jessica Rothe), joins a humanitarian mission travelling by boat down an Amazon river to deliver medicine. She and the boat's engineer, Lena (Kiana Madeira), clash with a group of contractors surveying the forest, a fight ends in an accidental death, and the dead man's brother (Logan Marshall-Green) comes after them. Then there is the river itself, and the giant serpent of local legend that gives the film its title. That is the first act, and all you need.
The reviews keep returning to the same strengths: a sweaty, claustrophobic atmosphere, a creature that is held back before it is shown, and a tone that plays the premise straight rather than winking at it. Dread Central reaches for Jaws, because the film builds dread from what you glimpse and from the boat's isolation before it pays off.
"takes the crown as the meanest, bloodiest, scariest giant snake film to ever slither onto screens"
Matt Konopka, Dread Central
Reviewers also single out the cast for committing to a script that asks them to choose, again and again, whether rescuing someone is worth the risk to themselves. TheWrap adds that the film's thread about colonialism and development in the rainforest gives the monster something to stand for.
Even the admirers say the story is thin. TheWrap's critic puts it plainly: there is not a lot here from a story perspective, and he warns against over-praising a film for being good by a low genre bar. Dread Central finds the pace drags when the snake is off screen, and the human villain less interesting than the animal.
Here the critics split. The Federal finds the withholding of the creature timid rather than tense, calls the film neither effective elevated horror nor a consistently fun creature feature, and says it is "time-pass at best". It also faults the cutting in its suspense scenes and a handful of darker themes left undeveloped. Same restraint, opposite verdicts: one critic reads it as craft, the other as nerves.
