Hey, finally I found a movie on Stan that I consider above a B grade.
It's the 2007 Spanish haunted house movie The Orphanage.
I had vaguely remembered that it had good reviews when released, and I see now that it scored 87% on the semi reliable Rottentomatoes.
I agree with most of the review extracts I can see at Rottentomatoes - it's frequently suspenseful, surprising, and so well crafted. It's hard to describe the ending without giving anything away - but it hits with quite an emotional punch.
I think it's pretty rare to find a scare movie that is emotionally resonant - although, I must say, I think that that was the reason that Poltergeist was so successful. You really did feel the emotion between the parents and the daughter in that film, too. [And, I will add, that there is one sequence in the film which some might say is very derivative of Poltergeist - but I found it entirely forgiveable. In fact, now that I think of it, thematically the movies are perhaps a bit similar in a more general sense, too.]
