Sci-fi/Action without story? Pathetic...

Rating: 3/10 (3 March 2014)

This is a sci-fi movie, so at the start, I just don't want to list all the problems, why this just cannot work from science point of view (pretty long list). This is just OK at a science fiction.
My real problem is with the story. The lack of story, actually. Classic fairy tales have more interesting ideas than this film has. Most of them; I just can't tell any exception for now.
The effects and action is pretty shiny, they took a lot attention on that point. But why? It doesn't make any sense.
So this is about a separated "island" for the chosen, when the poor on Earth suffers from diseases and pollution. The characters are designed as a child would do, and they keep on this level until the very end, where it's not Bruce Willis, but Matt Damon to save the world this time.
Is there anybody, who read the idea (not the script, that have to be just a lot of work, maybe even 6-8 pages;) ) before making it? For me, this just seems pretty useless.
