It might not be technically perfect in composition and the like. It might not be lit exactly right. Your gear's operating at its limits with too slow a film, so the lens is wide-open and the shutter-speed's as low as it'll safely go.
It's a snapshot in the moment, but it's still just about in focus, all your settings were still close enough to right, and you got it with your last chance on your last roll of film for the day.
