I saw House of Voices recently and it was a seriously mixed bag. The acting and cinematography were pretty good, and there were definitely some really freaky, creepy moments. Shots from that movie stuck with me a lot longer than most horror movies. They did an excellent job of setting up a creepy environment and communicating a feeling of helplessness and a fear of the unknown.
Having said that, I thoroughly hated the protagonist, who at least to me came off as a life-wrecking idiot who acted entirely on impulse and never wasted a moment on things like contemplating the consequences of your actions or listening to advice from the people who know the secrets of the haunted house. By the end of it I was yelling at the TV, "please let her die! Give me this, let her die!"
And - spoilers - she did. She also got her baby killed, which I think we're supposed to view as a good thing because now they get to be spirits together in the orphanage forever and she gets to be a kind of mother to the ghosts. Except that's an idiotic premise; if she chose to kill herself to mother the ghosts, that'd be her thing, but if she gets her newborn baby killed so she can keep it forever in the twilight between life and death, I have a problem with that. That's a lot like what Andrea Yates did, and you know, even people who shared her religious beliefs thought she was a monster.
So on the whole, scary movie, infuriating protagonist.
