Weren't you disappointed with the last seasons of Suits? I think I dropped in season 5 because it got really not so good
Suits was good for a couple seasons but I think it fell in to the same trap that most other successful TV series fall prey to... they throw these ideas at the wall with a clear idea for the first season MAYBE the first two seasons, and if it becomes a hit and lasts longer than that, with no real long term story/plot, they just keep manufacturing stuff on a week to week or season to season basis. See examples like Dexter, Lost, Heroes, etc... Lost for example is a HUGE perpetrator of the "Very clear, intriguing, first season story, but then after that it's a revolving door of new random problems, new enemies/antagonists, etc to keep viewers coming back" and the random stuff they come up with is often that, extremely random and pointless. How much random crap was there in Lost that would straight up appear at the end of an episode and they'd be like "Tune in next week to find out what's going on with this polar bear on the island, or this giant white mist that is floating around killing people, or the mysterious underground hatch/bunker, blah blah blah". The Walking Dead is another shining example of the revolving door theory of story & plot lines
