I don't understand the concept of a "plot hole." When I see what other people tell me are these things called "plot holes," I don't think, "HAHA! TEH SUK!" I think, "Huh. That's interesting. I wonder what that means?" And I'll think about it for a bit, and it'll usually inspire some insight.
At least, I think that's what I think. I can only assume that this is what people are talking about. People will say, "Oh, that movie had so many plot holes in it, nothing made sense," and I will have, literally, no idea what they're talking about.
This happened with Transformers, (Great movie, go see it.) which inspired this line of thought. I am told that this movie's plot is full of holes. I have no idea what this means. Where are these holes? Would someone care to enlighten me on this topic?
And, heck, does anyone have an example of a plot hole in a general sense? In a movie, in a book, anything. Examples are the key to learning!
