Is "Orphan" a good movie to rent?

I am gonna rent "orphan" tomorrow on On Demand, and I wanna know what you think of the movie. Is it good? How scary would you say it is, on a scale of 1-10? Is it worth $2.99 lol? so, anything that you have to say about it (positive or negative), tell me. I wanna know what other people think. Thanks :)
