What people are saying
Updated nightlyReactions are all over the place for this Amazon creature feature, with a slight lean toward the negative. It's a standard fight-for-survival mission, but the monster, Boiúna, is widely panned as a generic giant snake that fails to impress. While the visuals get a decent nod, the story and pacing are criticized for being thin and slow. Most of the cast, including Logan Marshall-Green's Brennan and Jessica Rothe's Alli, don't land well with audiences, and director Mike P. Nelson is called out directly by those who talk about him. The one bright spot is the acting, a few people note it's fine, but that's not enough to save the trip.
