LinkSounds like it could be a cool movie. I like when a time travel movie deals, in great depth, with the consequences of action/reaction with past/present. It's cool to see how one small thing can effects so much.
Ever been driving on the highway and come up on an accident and wonder to yourself, "If I hadn't done a certain thing before leaving the hosue that would have allowed me to leave sooner, like eat breakfast, would I have left just enough earlier that I would have been in that accident?"
Every action has a reaction.
The only thing I wonder about with this movie is they seem to focus on accidentally killing something that wasn't supposed to die, in one case a butterfly. They go back in time to hunt dinosaurs with the understanding that dinosaurs are going to die anyway so I shoudl have no "ripple effect" on future events. They accidentally kill a butterfly which apparently would have lived and done whatever in the evolutionary timeline.
Well, my question is, unless they go back at the exact moment the dinosaur is supposed to die then they can change things by just the opposite reason as the story's plot. Instead of accidentally killing a butterfly, they are preventing the dinosaurs from doing what they're "supposed" to do until they die naturally. So what if that dino they shoot was supposed to step on a few butteerflies or bugs or killed another dino that would have eaten some bugs, etc., but didn't because it was killed before it could... wouldn't that have just as many adverse effects?
The idea of the story can certainly make you think a lot about cause and effect.
