Query: Nothing Explained

What was most upsetting about this movie is the fact that nothing is explained. Nothing is resolved. And if you're content with watching a movie and not receiving all the information necessary to understand WHY things are happening, then you'll be ok watching this. Yes it is somewhat creepy. Yes, Naomi Watts is a fantastic beautiful actress and does a great job along with the boy who plays her son. Yes, the plotline was a fantastic one that could have been developed better.But in the end, you are left with a movie that doesn't explain why the "entity" is killing people, where this "entity" came from, nor how to defeat it. Unless they come up with a sequel/prequel movie that answers my concerns above, then this movie will have been a waste for me.
