It woulda been better to compare American Me vs. Blood In Blood Out. Since Blood In Blood Out was a straight up copy of American Me. Neither of the two movies you listed are based on true stories. Although the movie that BIBO copied (American Me) was based on a true story about how the mexican mafia first started. Which also caused the Mexican Mafia to put a death sentence on Edward James Olmos for telling the story of how they first became a powerful gang and he actually had to pay them money so they wouldn't kill him. But back to the topic, i actually like Mi Familia more than Blood In Blood Out. Mi Familia captures the lifestyle of many mexican families in Southern Cali and many mexican families can actually relate to the money because they have dealt with the same situations as in the movie. In example having family members that are here illegally, having family members in jail, having a brother or sister go to school then they feel like their heritage and culture are embarrassing once they get somewhat successful. Mi Familia also has a more well known cast compared to Blood In Blood Out. My Family has Edward James Olmos, Jennifer Lopez, Jimmy Smitz, Jacob Vargas, and even though she was uncredited Eva Mendes was in there too.
