They ran through the Bloodline ending in short time. Roman should have faced Solo in Tribal Combat at WrestleMania, not the Netflix premiere. The whole storyline was building up to that one match. Then you can have Solo leaving, Jacob stepping up and losing faith in Solo, and those two having issues with each other. Maybe they end up having a match at next year's WrestleMania.
Instead, Roman wins and the storyline ends. The new Bloodline isn't a threat anymore and nobody cares about what they do next. Roman gets the ula fala back, but none of the things that come with it. No power, no abundance, no family. The only thing that happens is Seth keeps him from competing in the Elimination Chamber, then he gets upset because Paul owed Punk a favor and he goes far enough to where Paul wants nothing to do with him. Jey and Jimmy are doing their own thing. He never gets a rematch for the title he held for over 1,000 days, he has no Wiseman, no one to help him out. He might as well retire at this point because he did everything he could possibly do.
Meanwhile, the Solo/Jacob partnership ends after a year. The new Bloodline really doesn't achieve anything noteworthy. Jacob won the U.S. title, but that wasn't really an accomplishment for the family, it was an accomplishment for him. Half the new members are hurt, Solo is more of a comedy guy than a serious character now, and Jacob's gone from the Bloodline. I didn't see it at the time, but Cody winning the title really put an end to the group. They can continue doing Bloodline stuff, but nothing they do will ever come close to the OG run.
