Godfather is a fuckin series of movies you can't really say that one of them is better because they belong together to get the whole movie.Just get the DVD Box and watch them after each other.
For some ghetto nigga gngsta shit get Gang Tapes,Blood in Blood out,Juice,Boys in da Hood,Menace to Society etc. But those movies don't really twist your braincells,it's just dumb ghetto shooting,they ain't got any class.For class get the Godfather series.
