I hated Jotaro at the beginning after having Joseph I just couldn't believe that spoiled brat's attitude, I mean the way he treats his own mother, his "I am the most badass in town " behaviour, I hated him, but I warmed up to him, he gets better little by little probably because all the things he goes through along the journey and the camaraderie he develops with his new friends, heck, Jotaro and Kakyoin are amazing friends yet so different in personalities that if it wasn't for the incredible circumstances that brought them together, I can't see them becoming friends of it wasn't for that, that 'so how insufferable Jotaro was at the beginning, he changed but still he'll never surpass Joseph in my heart as the greatest Jojo ever.
