Yeah, they definitely took away certain aspects of the show that gave it a reason to exist. I feel like at some point (maybe last season), the writing became more inconsistent and the path that Ghost was on originally kept changing repeatedly. There was a time where Truth actually mattered. It was straightforward too: Ghost is trying to get his nightclub going, but he still has one foot in the streets. By season three, he already had Truth Miami, and he was making deals to get Truth Vegas and Truth Dubai. Then Angela arrested him and the direction of the show shifted.
I like season four, but I think that's when the show started changing from what it was before. Truth no longer mattered after Ghost was arrested and they introduced Tate. Suddenly, all Ghost cared about was the Queens Child Project. This went on for literally two seasons until he decided to become a politician. Tariq became a more important character to the detriment of everything else. And they finally pulled the trigger on Dre becoming the bad guy, but they didn't follow it up well enough in season five.
If you look back at season four, the main characters are all in a good place until Raina gets killed. Ghost was exonerated and started working on the QCP. Tasha fell for Silver and was making plans to divorce Ghost so she could be with him, but their relationship was still more positive than it was this season. Tommy found his father, and was starting to do business in other cities and with the Jimenez Cartel. Angela got a big promotion at work. It felt like the characters were growing up and moving on to better positions in life.
But because they started investing in Tariq long-term, Raina was killed, and whatever growth the characters were getting was stunted for good in seasons five and six.
