From the very beginning it was pretty much non stop action. She kills this elk with an arrow and then her dad attacks her. I mean, honestly, the opening couldn't have been much cooler. Even though I felt like this was pretty much a textbook example of an action movie, what made it great is the fact that it still had some symbolism to it.
I don't want to give anything away but it touched on being different and innocence a little bit. There was sort of underlying point that if you teach someone their whole life that Coke is a healthy drink then they will treat it as such until they somehow find out differently. We tend to say that people are only products of their environment and that is very true. People will normally grow up to be just like the people they were raised by, but there are exceptions. That's where nature vs. nurture comes in. Some people just want to do right or do wrong. You could put them in almost any environment you want and it would almost never change. To me, the real argument is that both are right.
