The premise of "The Hallow" is nothing new: a family in an isolated house in the woods. Strange things start to happen. Is there a logical explanation (unfriendly neighbors who want the family away) or is there something supernatural in the forest?
Unoriginal concepts in the horror genre are not a problem per se; old stories can always be told in new, refreshing ways (see "Insidious" or "The Conjuring", for example). But "The Hallow" doesn't have the energy to keep things interesting until the end, despite a strong middle act and good performances from the cast.
The film starts OK, then it gets better and more tense. Some sequences in the second act - when it's fully revealed the cause of the disturbances - are genuinely frightening (plus, that poor baby suffers a lot). But then the script gets lazier and lazier, unfortunately. Inconsistencies abound, jump scares replace real tension, and by the end I was just bored. It's a pity. It could've been a small horror gem.
