It doesn't say much about this movie. . .
That half the threads here are about Lizzie Olsen's cleavage. And not even her actual BOOBS, which can be seen in all their glory (along with her not-inconsiderable butt)in "Martha Marcy May Marlene" and the stupid "Oldboy" remake. No, it's only her CLEAVAGE that has distracted so many from the ineffective horror.
I suggest that some of these people go watch the scenes from one of these other movies (actually "Martha" is a very worthwhile film) and thoroughly drain your dragon. Then watch the ORIGINAL "La Casa Muda", which hardly has any dialogue and won't require reading many subtitles.
