Just a few reasons why-

- having all the rappers be the same character = cop out.

- taking out any specific references to the timeline or whatever may have been a good idea on paper but ultimately made it boring and unrelatable.

- Phonte's line about occupy my streets sticks out like a sore thumb in context of point above.

- Most importantly= the story/concept is so overly simple its not interesting nor unique. You could tell someone Game Theory is the same concept and it would make as much sense.
