Thanks, riff, for drawing my attention to this line!
Y'know, at first it sounds stupid, but repeat it enough times in your head and its simplicity is kind of zen-like. You could reduce all the ills of the world down to "It's just a thing." Including this movie.
So, remember, next time an eagerly anticipated film doesn't meet your expectations, just take a breath and think the crystal words: "It's just a thing."
