I'm probably a minority in this, and honestly not much a movie person in the first place, but I tend to enjoy movies more for the settings and occasionally characters they establish then anything that happens to them. The context more then the substance. While I'm not likely to gripe about such and such not being realistic, plot holes and inconsistencies I realize later often... for lack of a better word taint the enjoyment I might've had with it earlier. So I find them a bit important, and am thankful when I know to avoid a movie because of them, as there's few things that illicit the same sort of disappointment as watching a movie, loving it, watching it again and coming away frustrated with it's flaws. Those who nitpick the things you only notice when paying close attention on multiple viewings can be helpful to some people.
