I guess this proves I'm not a teenage girl.

Rating: 5/10 (11 May 2015)

I really wanted to like this, but it was a serious letdown.
I never read the book, so I can't comment on it's veracity to the source material, but as a movie, the acting is flat, the jerky camera movements were nauseating, and the material is highly, highly derivative (The Lottery, Lord of the Flies, Battle Royale, a bunch of old-time Star Trek Episodes, Death Race, The Running Man, countless other dystopian sci-fi stuff, and so on).
While the utter lack of originality is very disappointing, I do give it extremely high marks for production values. The only really novel aspect of this action film is how directly and manipulatively targeted it is to teenage girls--unfortunately, I am not a teenage girl, so I just couldn't really get into it. I'm used to stuff manipulatively targeted to teenage boys, or at least those with the minds of teenage boys (like me sometimes, I suppose).
As hackneyed and littered with convenient and predictable plot devices as this material is, I'd still bet that is very successful with its target audience. I'm not going to make any nasty comments about teenage girls, but there is no possible way I will be watching any sequels.
