ANIMAL KINGDOM

When watching certain violent, aggressive and destructive films I ask myself, what the hell are they useful for? are they trying to send a message, warning us that this isn't the way to behave because we are too stupid to realise by ourselves, I doubt it, and if that isn't the case, then these uncertain ambiguous crypt messages must have another proposal hidden which we overlook.
Maybe they need to remind us the times gone by when in caves and hunting to survive we were lethal when organised in groups, our prey had no chance or very little, could that be the message, its to say, haven't we changed since then?
I personally think that humanity has changed very much, but who knows maybe I'm mistaken or maybe we've just perfectioned with the centuries the way of doing the same but with fewer risks involved, calculating more efficiently but with the same objective, the prey.
But the question is, who is the prey now?
