Let's make this clear, from the outset this is not a pleasant or enjoyable movie. It's about a supposedly bad (hates her adoptive parents, usual rage-against-life stuff) teenage girl meeting another teenage girl who turns out to be an out-of-control psychopath. On the surface the story shouldn't be terrible, it could work, it has worked. But not here, not for me anyway and I can understand people who give it a rating of 1 or 2. The characters are one-dimensional and ugly; there are no quiet moments explaining behavior or motives and absolutely zero relationship development. I didn't care what happened to any of these people and wanted to turn it off by the thirty minute mark. I hung in and watched the psychopath kill and attempt to kill numerous characters but found myself rolling my eyes too many times to count.
Dumb characters, dumb script. Silly, silly movie. To each their own and some people might like it.
