Yeah, JoJo dubs usually aren't that good. The Main Antagonists usually get spectacular performances though, Dio, Kars, DIO, Kira and Diavolo all had fantastic english dubs. The minor antags though, usually get shakier performances like ol' Maxxi-Pad here.
That, and a lot of JoJo's cheesiness doesn't translate well into languages you actually speak. It's one reading a character narrate their own thoughts and feelings out loud or hearing them doing it in Japanese, but hearing it in English feels all kinds of awkward for reasons I don't really know how to put into words.
