So I'm a little confused (spoilers)
I'm just confused about a few things. Maybe I just need to go back and re-watch the film, see if I missed anything, but I just didn't understand WHY exactly the lady was killing all those people? I understand why she killed the Prof. and that inspector guy, but why kill the girls? Did she do that because of the trauma from her being raped?
I honestly feel like having the deformed son show up was just a way to add "shock value," because I didn't quite understand how that really contributed to the plot. I mean, how was killing all those people protecting her son???
Again, maybe I'm just dumb and need to re-watch the movie, but I'm just a little confused. Or maybe I'm just reading too much into this? I have no clue.
