Because there is actually something very interesting in Goodfellas, how the style of the film changes as time goes by and based on the mental state of the protagonist.
Justin Salinger showed up one day with a pink cowboy hat on and everyone else got really annoyed because somehow he'd managed to get the pink cowboy hat.
It's interesting actually, what's gone on with that footage, and also what happened with the footage from the war in Afghanistan, is that our news reporting is pretty much along the lines of pornography now.
And it says something about our level of disassociation, that we can provoke these wars abroad but we're not allowed to see people get killed as a result.
In Goodfellas they have this one scene where the camera goes down some steps and walks through a kitchen into a restaurant and the critics were all over this as evidence of the genius of Scorsese and Scorsese is a genius.
