Did anyone else get the message that... [spoilers]
emos are undeniably bad?
The whole film seemed to be based on one girl being useless and emo since she loved her sister, and then for some reason decides that both of them committing suicide would be the best option...
Then of course this selfish way of thinking causes the sister to go crazy and kill everyone apart from Tim (who semi caused all of the deaths for the video game thoughts).
Personally I didn't really find the film confusing (maybe because I didn't understand?) but to me everything did just boiled down to the suicide of the girl in the glasses?
