As a fan of jojo, part 6 was a major disapointment to me, the main characther and the sidekicks are straight up worse versions of the stardust crusaders. The concept of being in a prison is well handled, but Father Pucci just tries too hard to be a good villain, and ends up being a bad dio (Funny, huh?).
There's just so much bullshit on certain chapters, and althou Jojo is known for a lot of bullshit things, part 6 takes it to an ungodly amount of protagonism, ex machinas, plot convenience and others.
The ending was rushed, and it shows, Pucci had so much more potential to be a good villain, but failed miserably in the end.
At the end of the day, Stone Ocean had a lot of potential, good visuals and a good roster of characthers to explore, but failed at delivering a good jojo part.
