Well it is not just love that hurts ... so no pun intended. Also movies like this one remind me how lost I would be without the whole system that has been set up ... as in I don't think I am cut out for the whole hunting and outdoor thing - outside of cities.
That all said, the movie is keeping it as real as possible. Humans do their best to survive ... and mostly stick together when danger is coming up. That said, anything personal can also be quite dangerous ... because it will come to light ... as much as we have that survival instinct, we as humans also have that self destruct inside of us ... anyway.
The movie is well structured and while you may think this looks like by the numbers ... it does have a few surprises along the way (no pun intended) ... just don't freeze on it ... or in it!
