Given scene/plot descriptions from movies or TV shows, and given a specific question about the scene, summarize the question into a title
Example: At the beginning of the movie Gangs of New York, Priest Vallon tells his son not to wipe the blood of the blade after he's cut himself shaving, saying "The blood stays on the blade". I've watched the movie multiple times, but can never find what the meaning behind that phrase is. Anyone able to shed some light on this?
Example solution: What's the meaning behind the phrase "The blood stays on the blade"?
Example explanation: A person gives a detailed description about a scene from the movie Gangs of New York and asks the meaning of a said phase in the scene. The question is summarized as What's the meaning behind the phrase "The blood stays on the blade"? for easy indexing the next time someone searches for a similar phrase

Problem: I've noticed a trend recently where, in a particularly violent scene, blood will end up on the lens of the camera. It's not restricted to blood; it could be water, if it's a particularly stormy scene, or mud in, say, a battle. Any kind of liquid, really. The point is that the scene is usually pretty charged. Has this become fashionable and, if so, why? I don't recall seeing this as much when I was younger -- but maybe I just didn't notice -- and, for me, it breaks the suspension of disbelief. I presume the production team are in control of the filming enough such that they can choose if or when this happens, rather than it being accidental. Is it a meta thing to try to suggest to the viewer that the scene is so chaotic, that even the producers can't control it?
Solution: Blood on the lens
