nice try but
There are a lot of other movies in this one.
They have done their homework. It is not that I dismiss quotes in general, in the end there is never nothing 'new' everything is built on history, but then one have to use them in a good way, create a strong personal vision. And I have a difficult time seeing this in this movie ... It looks like a puzzle of 'good scenes' from a lot of others work. A fluffy story and fluffy characters.
I prefer 'Godfellas' over this one, it has the same tone & feel, but is superior in a lot of ways (and not only for the choice of music from the 'belle epoque'), or the barbeque, or the showing of the house when she is pulling the brothel (I am typing while watching) ...
Could be it's younger brother that is looking for his own style by trying to copy key elements that he has seen before ...
