No Hayden was not just awful in Attack of the Clones and Revenge of the Sith. His acting in Jumper was laughably bad to just plain mediocre.
How could you find anyone more dislikable except maybe for Shia Lebouf or Chris Pine.
Seriously i get that chicks think he is hot, but besides that he cannot act to save his life. Even in a fucking high school play he probably would make you want to get up on stage and start punching characters.
