What do you think he needs to do in order to get back in the good graces of you and everyone else?
I know the knee-jerk reaction is to say something like "release the original trilogy untouched on DVD/blu-ray in good quality", but is that really all there is to it?
That's exactly how he can redeem himself to me and other fans that have been wanting that for so long, but with all the extras too. Then he can come back to the Jedi side and the circle would be complete.
in addition to your suggestion:
Turn himself in and pay whatever penalties are in effect for false advertising the 2004 DVDs as "all three classic films" and refund everyone who bought them.
issue a public apology for his shoddy, unprofessional work in putting half-assed sloppy changes into the OT, and ESPECIALLY issue an apology to the estate of Sebastian Shaw.
That and never make another movie again and I'm good.
Yeah, I don't think "redeem" is possible. Not with the new trilogy and Indy 4 out there. Those can never be erased, and making another trilogy or Indy 5 would likely make matters worse. Seriously, I idolize Harrison Ford, but another Indy adventure when he's 70-years-old? It would take an amazing screenplay to make that work. And episodes 7-9, how can they be made without Luke, Leia, and Han being played by new actors? Motion-capture? No, fans would be even angrier. He dug his hole and filled it with our money. He doesn't care about quality at this point. Releasing a Blu-Ray of the originals would be a degree of atonement, but not enough for redemption.
