Just curious as to why questions that point out plot holes are downvoted so much?
Because pointing out plotholes is boring, and most of us that have been here a while are beyond sick of seeing them, for the following reasons:
Most of them are not plot holes. A "plot hole" is a very specific term for a place where there is a direct contradiction between two parts of the script that happened on-screen. Just because something isn't explained, or seems unreasonable, or unlikely, etc., doesn't make it a plot hole. It just means you have to use your imagination to fill in the gaps. Which is the whole point of fiction.
Most of them have no "official" answer. They're just things the writers didn't think were remotely important enough to bother putting in the script.
Many of them have very obvious "unofficial" answers, all of which are equally valid and none of which affect the plot in any way.
And my personal pet peeve, historically far too often, the person asking the question is not genuinely looking for an answer, but rather just trying to show off how smart they are by pointing out what they think is a mistake in the movie. We have MovieMistakes.com for that nonsense. Most of us have noted the same mistakes in the movie already and just brushed them off as irrelevant, so we have no interest in seeing them brought up over and over, especially as they usually end up generating way more noise than light (since the OP will often refuse to accept any answer other than "you're so smart, you found a plot hole!".)
