Entirely watchable supernatural thriller. Michelle Monaghan moves her family out to the country, where her young son is bit by a sick dog and subsequently develops an overwhelming thirst for blood. It could have gone a lot of different ways, but well-played with low-key intensity as the family goes further and further to try to keep their son alive and satiated as he slowly turns into a monster. Good performance from the young kid, too, playing the son trying to deal with urges he doesn’t want but can’t fight. And it has maybe two fleetingly short but kind of creepy moments, which is more than the zero you usually get from movies like this.
I’m rating this a little highly by putting it under “je nais se quois”, it’s not necessarily anything special, but… it’s watchable for sure. It’s not crap. If there’s a lot of crap to choose from to watch, and there’s this, definitely go with this.
