Almost 1 AM here, my work for today is finished and it's the first time I have a chance to see this flick,
It definitely has his trademark / dynamic style of shooting although there probably aren't yet such an incredibly mastered dramaturgy / wit and changes of pace.
It definitely has an atmosphere, one of the movies that always makes me willing to hit New York, Harvey Keitel in the leading role is excellent as well as Robert De Niro as the "Johnny Boy".
An overture to such classic cinema fundaments such as "Taxi Driver" or "Raging Bull".
I could guess there a strong influence to Tarantino in his directing style and raw / furious pace / uncensored dialogues and indeed as I just checked imdb he lists Scorsese and especially taxi driver as one of his influences.
