What this movie REALLY is about [NO SPOILERS!]
So, the tagline reads something like "salvaged container making violence, terror and crazies come to town. also mother daughter thing"
And sure... It is about that.
But... I found it more like a "mother gives up daughter, regrets, gets a chance to salvage relation. also container, violence terror and crazies."
SPOILERS AHEAD
With this change of perspective all need for thorough explanations are no longer needed.
Kinda like "the road", "book of eli", "I am legend" etc.
What is left is a dark - Mother givees up daughter, [build up tension], daughter DENIES mother, mother makes effort, salvation .. and TWIST mother dies - movie.
But also.. I think, what makes it work is the fact that you go in expecting the first tagline but instead get something else.
Because, frankly, as a movie about the second tagline this one kinda sucked.
But as a mix, and 'cause the lack of similar movies, I give it 6-7 of 10.
What do you think?
