Just saying. I hate voice-overs because they are insulting to your intelligence. Some voice off-screen telling you what you are seeing and adding superfluous narration and explanation. While at least one film I like, "Goodfellas," uses voice-over, this does not make the film any better than it would be without it.
There are these other gangster films that rip Scorsese's film. Those are doubly worse, because they are voice-overs and they are lame imitations of "Goodfellas." One of these lame imitations, I think, is by Scorsese himself. He should have used it only once.
