Hey guys,
I have read many comments about people hating this movie.
I guess instead we have to look up to the "positive point" of view. The end of the movie itself tells you that both family gets in trouble because of such a silly lie!!! Kayla's parents get in trouble as they accidentally kill Brittney's dad and Brittney lost her dad because of that mistake she made.
In this movie everyone lied in order get into their own comfort zone. Kayla and Brittney planned and lied to their parents. Whereas her parents in order to protect Kayla hid a lot of things etc...
Moral is "A lie may take care of the present, but it has no future....."
