A "new " Voice

According the the text, John Singleton's Boyz n the Hood, gave African- Americans "an audience in a way that rap had done in music." The movie reflected the ghetto, violent lifestyle of three young men on three different paths. And in each case it was either kill, be killed , or barely make it out. Like most rap the major themes are violent, abrasive, and associated with some form of dysfunction or nontraditional families. For example, being in a gang, being raised by a single parent etc. I believe that the movie was great because it was relevant to African-Americans culture and experiences but not all. Why is that in African-American culture there are not many other movies that give us another voice? How long are the themes going to be associated with "struggle, dysfunction, hope??? Was Boyz n the Hood a good medium to establish African-American identity?
