Query: it could have been much better

We were disappointed in the movie. The acting wasn't bad and it looked as though it had potential but there wasn't enough explaination given as to why this was all happening. Also, there wasn't alot of background/relationship information given Layla and her brother/mate.I guess it is suppose to be suspenseful because of the lack of information provided?? The fear of the unknown...I don't know but it just seemed lacking without it.A guy and girl who are brother and sister but are oddly intimate apparently go house to house and live in it...why do they do this? The question is never answered.Also, the neighbors, family, friends, ect. never think to report something suspicious? So the duo have been living in peoples' homes and the police has never caught onto them? Oh yeah...they move from place to place frequently....but why they do this is never answered.There are more unanswered "why" questions but I don't want to give too much although there isn't much...
