I knew nothing about this movie... (SPOILERS!)
I just punched it up on Netflix. Poster art looked cool.
In the first five minutes, I thought it was going to be a remake of "Drag Me To Hell", when the bank chick denied the old lady's loan. I was expecting Halmoni to put a curse on the bank lady. Doesn't matter...she's cursed now anyway.
My favorite character was the police dude who showed up after the little kid died. That was quite a thorough investigation. Then later on he gets sledgehammered in the ballsack. He gave the textbook Comedy Nutshot Face. Cross-eyed, and "Ooooooofff...!" Dead.
