I think the main point of the alternate reality was to show just how much of a trap the hood is. Franklin fought to go to school & have a better life, made all the right decisions & still ended up back in the same spot with the same hardships around him & his family. Even trying to take the "square" route he almost lost his life, still has a system trying to derail him (school vs the police), and his family is still struggling to make ends meet.
around that time a lot of the messaging from mainstream media made it seem like it was a easy decision to not get caught up in what came with crack. "Just say No" what we've seen with Mel becoming a fiend & Franklin in that alternate reality, is that in a lot of cases people had the right intentions & motives & still get caught in the streets due to the surrounding circumstances.
the entire staff from writers, directors, Cinematographers etc etc showed their *** this season. This season def took that leap for me in regards to this show possibly becoming a classic.
