2.5/4
Mike P. Nelson’s rip-roaring creature feature is surprising both for how attuned it is to the rhythms of its setting and for how little interest it has in condescendingly exorcising our white guilt. Go to Full Review Meagan Navarro Bloody Disgusting Sep 18, 2026
Director Mike P. Nelson breathes new life into the niche animal attack category with relentless suspense, a mythic movie monster, and a cast of characters worth rooting for. Go to Full Review Preston Barta Denton Record-Chronicle 4 days ago
