I don't think it's necessarily Jar Jar's personality or voice or antics that annoys people. I would have been fine with him if he'd just been a silly side character who showed up every now and then for some comedic relief. But Jar Jar was way too important of a character for someone so seemingly incompetent and he was constantly shoehorned into scenes had no business being in. Why the fuck would a bumbling buffoon become a galactic senator? Why would this aquatic alien accompany the Jedi who are exploring a desert planet? Why is this goofball following the Jedi on a rescue mission in an enemy occupied city? Why do the serious Jedi doing serious things always tolerate him nosing into their business?
Seriously, the only plausible explanation for the sheer amount of seemingly illogical screentime and undeserved importance Jar Jar has is that he's a secret Sith Lord who is mind controlling everyone around him. Otherwise nothing about the character makes any sense whatsoever.
