I think there are some implausible scenarios here (why do they live on an island surrounded by water with no boats? Why doesn't Isaac remember anything? Where is all the food? Why is the house so run down? But most importantly, who would agree to that situation?) but even if you look past those, the plot doesn't quite come together in the end.
It's a thriller that decides, at points, to become a horror, and I think it should be one or the other (it should be a horror). All the stuff about the planned murder and the double crossing and what-not just don't gel for me. If it had been about an eccentric family living on a weird isolated island and a witch it would have been ok, I think. Maybe focusing more on the mother and re-animating her. I think then it would have been alright. But as it is it just didn't make sense.
