Tosh. For about three quarters of this movie there’s a half decent story in there. The horror elements were quite scary, the domestic scenes engendered sympathy, and the mystery was quite intriguing. Unfortunately for the audience it all falls apart in the endgame and the explanation does not live up to all that has gone before.
As to the special effects they were an unhappy mixture of visually ambitious, hokey, and poorly executed. It’s like they didn’t have enough funds/time to put the finishing polish on.
