Would having some snot-nosed kid play him be any worse?
Well no and I think it's a foregone conclusion that either that kid or Morrison will play him again at some point (maybe as soon as the Han Solo flick.) But if RO could redeem Vader after his emasculating appearances in ROTJ and the PT then I've got to assume the same *could* happen for Fett, but only if they did him right. Daniel Craig's ST voice was pretty close to Wingreen Fett and he had a decent amount of swagger in the costume. Karl Urban in "Dredd" mode could also make an awesome Fett.
Not that either of those two options are remotely possible but I do think that they could restore him to his ESB glory if they were actually willing to do whatever it takes.
