People have an irreverent relationship with nature, although we fear it. That's because even if we damage it, nature cannot be controlled; please refer to Ian Malcolm. But that fear is embedded in our DNA, from ages past. We've done our very best to avoid our natural predators, at all times. So, it's no wonder that we have such a fascination with them.
There's a long history of movies with killer animals, and the majority of them are poorly made. However, animals are both notoriously primal and everyday things. We coexist, and when we test our relationship with animals, we often underestimate them.
