Luke Skywalker has a changed line in the next revamped edition of ESB
'Bad acting runs in my family, Leia. I have it. My mother had it. My father had it. My sister has it.'
Seriously, I don't think it was as bad as some are saying. I felt Hayden was probably a better actor than Hammil. Granted, that's setting the bar low, but when did we ever let subpar acting from a Skywalker get in the way of our enjoyment of a Star Wars movie.
Okay ... young Anakin (forget the actor's name) really pushed it, but you get the idea.
