I will give Focus Features this: the trailer for The Book of Henry is not misleading. When I first saw it, I couldn’t believe that was the movie. How was a movie about a precocious, 11-year-old who’s helping to raise his little brother and his immature mom also a film about the mom trying to assassinate their next-door neighbor because he’s molesting his stepdaughter? Those are two completely different movies. It’s like blending Capri Sun with absinthe. And yet that’s pretty much the movie director Colin Trevorrow made. He plays Gregg Hurwitz’ script completely straight, and what could have been a story about a child unable to come to terms with evil in the world instead becomes a dehumanizing mess that rides its high concept straight to hell.
