Maybe I'm in the minority, but I liked Mobsters. Seen it multiple times.
Admittedly, it was far from perfect and deviated from known facts. But it is the only movie that I'm aware of that highlights the rise of the young mobsters to the top. And if one is interested in a movie about Luciano, the choices seem to be limited to Mobsters and Lucky Luciano.
Looking forward to the upcoming Luciano movie, hope it's a winner.
