Thanks to @QueenOfPlants for showing me this. So I'm in the editing phase of my first book, and whenever I try to fill up a plot hole, I feel like I'm just throwing matter into a black hole, making it even larger. Perhaps the trick is to just leave them be. How do you deal with plot holes? How big are yours?
I try to ignore them whenever possible. Worse thing you can do sometimes is draw attention to them with explanation that might not be necessary. Don't point at them if you don't need to. The reader might not even notice. Obviously that doesn't work if the hole is glaring, in which case, change the plot to eliminate the hole. Someone famous (Roger Ebert?) once said there are two kinds of plot holes, the once you notice in the middle of the story that make you leave the theater, and ones you don't recognize until you're driving home thinking about the movie. The latter ones are fine.
I enjoy movies that have gaping, bleeding plot holes and compensate by adding even more plot holes! Like Face/Off... just when you think it can't get any more nonsensical it adds another layer of ridiculousness. No apologies whatsoever. I admire that.
What's worse? Plot holes. Deus ex Machina. Abandoned plot threads. I think I'm a bit more lenient with plot holes!
