Reallllyyyy tough choice between 3 and 3.5— but you know what I think horror thrillers like this are hard to come by. On the other hand this movie did WAY too much, the dead kids helping the alive kid was a great premise (and wonderfully executed by the young actor in this like wow) along with such a disturbing performance from Ethan Hawke. Some super disturbing shots and sequences that pushed my rating up a bit. I just think the character of the sister felt like a plot crutch more than a character and that pissed me off.
Definitely engaging, definitely a one time watch.
