Look at the only demographic that largely rated this movie at 10...

Rating: 5/10 (14 January 2015)

...that's right folks, under age 18. To steal a line from Gene Wilder in "Blazing Saddles" (1974), "...you know...morons...".
The plot of this movie is ludicrous, that is, unless it was really Hitler's Germany where everyone at a young age was forced into a profession and working immediately. And some were committing genocide. And many young, working people had a decent chance to never see their families again.
Let me save you some time: search online for videos of Shailene Woodley. I had no idea who she was. She's young and pretty. If you spend 5 minutes looking at her moving in random videos, then you've seen this movie but probably with a better storyline.
In the future, evidently movies: suck, have horrible writing, have little to no character development, terrible action, are 100% predictable, and have an awful "love story" (if you can even call it that).
The ONLY saving grace of this movie? -- looking at Shailene Woodley.
Save some of your finite heartbeats and do not watch this movie.
