Ridiculous movie. It was a total waste!!! At some point I believed it was going to be promising but it ends up having too many things that don't make any sense at all. The first one being the teacher escaping Gladys' control after getting a lock of her hair cut off early in the movie. People say that aunt Gladys kept the hair so that the "weaponized" people could be directed against Justine in case she kept on meddling, but why on earth didn't she just take control of her and made her commit suicide or something if she realized that she was a threat.
And worst of all, by the end of the movie the main character ends up taking a back seat, she doesn't do anything relevant and gets lost with the laughable ending. Really, they wasted a very good idea, to me it seemed like they ran out of time and rushed everything to finish the movie, that being said their film resulted in a failure.
