Because I like movies and think characters should actually be characters not stereotypes or caricatures and its lazy filmmaking to do it any other way. Also, because according to Dre, his moms clearly was a huge part of his life so she should be allowed to do more than scream, yell, cry, and slap her son or tell him not to blame himself for his brothers' death. So to me, it's just lazy. Now like I said, they obviously had a lot of characters to juggle and deal with, because even Dre's character arc gets shortchanged for the sake of time and the same with Cube and how he became affiliated with the nation, why he chose to hook up with public enemy, etc. So shortcuts were taken, I get it, but that doesn't mean it's not an honest critique to point out when those shortcuts were taken and how they impacted the story.
