Stone Ocean sucks. The ending was a just anti-climax.
I hate how neither Joetaro nor Jolyne
could defeat Gucci in his ultimate final boss form, and the ghost baseball kid
is the one who defeats him and thus, triggering a BAD END where everything resets, Jolyne and co. were all alive, but in some alternate dimension, and didn't knew each other. They then bumped with each other in a car-ride. Baseball-boy then cried at the bad end
tl;dr Stone Ocean sucks, just skip it.
