Never Let Go

The reviews for Never Let Go have not been great but I was really intrigued by the trailer so I decided to see it last night.  Unfortunately, like several horror thrillers released this year, it begins well with an interesting premise and an escalating sense of dread but falls apart in the final act.  An unnamed mother (Halle Berry) lives in an isolated cabin in the woods, in what appears to be a post-apocalyptic timeline, with her twin sons Nolan (Percy Daggs IV) and Samuel (Anthony B. Jenkins).  She regularly reminds the boys of an omnipresent evil in the world, that only she can see which often takes the form of her abusive mother (Kathryn Kirkpatrick) or her deadbeat husband (William Catlett), and the only thing that can keep them safe from this evil is their home and the love they share.  When they venture into the woods to forage for food they must stay tethered to the house, literally with ropes, and recite an incantation before leaving and after they return (I wish this lore was explored more fully).  When supplies run low and the family faces starvation, Nolan starts to question everything his mother has told him.  Is the evil outside in the world or is it within the house?  I was really invested in the setup of a mother, who may or may not be suffering from delusions brought on by trauma, doing whatever it takes to keep her children safe and Berry does a great job at walking a tightrope between her character's protectiveness and unhinged paranoia.  Daggs and Jenkins are also very convincing and highly sympathetic, especially when the brothers disagree about the evil, because I didn't want anything bad to happen to either of them.  The atmospheric cinematography in the woods, the creepy production design inside the candle-lit house, and the menacing sound design create a palpable unease.  However, as with The Watchers, Longlegs, and Cuckoo, all of the tension is undone in the third act.  There is an M. Night Shyamalan type plot twist (that mirrors the one in The Village beat for beat) but the script doesn't commit to it and we are left with some incredibly confusing action sequences and a decidedly unsatisfactory resolution that leaves more questions than answers.  I found the ambiguity to be more disappointing than thought-provoking so I don't recommend this.
