It's definitely a drama/mystery. There are odd things that happen surrounding the daughter, Vicky, that you aren't suppose understand from the beginning, but will be clear once you reach the end. The story is confusing, because it's meant to be, because the characters have a intense history that you don't know. It's kind of like the sixth sense where you aren't meant to understand everything the 1st time you watch it, but with the sixth sense, you didn't really know you didn't understand everything until the end. I think the problem some people have with this film is, confusing things happen surrounding Vicky, and even at the end, they don't actually have a person say IN WORDS, what's the deal with Vicky, you just have to figure it out, but it's not that hard when you think over every thing you saw. Imagine watching the sixth sense, but they never specifically referenced ghosts, and the kid never said "i see dead people", but all the evidence of him seeing dead people was there.
