This is a great movie! Most of us have seen Jurassic Park, where the Chaos Theory is summarized by telling about a butterfly's wings, causing a tornado on the other side of the planet. Well, Bug is all about that (or at least something, don't worry this is no spoiler) I'm definitely not a religious type and don't believe in pre-destined stuff, fate, etc, but this movie surely makes you wonder if coincidence really exists...
further more, the acting and camera are excellent too, another prove that it's still possible to make a good movie without a zillion bucks
