I love the scene where Owen, Beru and Luke are eating dinner and Owen tells Luke that he actually knows who Obi-Wan Kenobi was.

It seems to open Luke up to a whole world he never imagined before. All of a sudden old Ben may know someone named Obi-Wan who knew his father.

And the fact that Owen quickly ends the conversation and then shares worried looks with Beru makes it all the more powerful.

That scene has some quality acting in it for just being a SITTING AND TALKING scene.

And as far as the PT is concerned. The only scene's that are redeemable to me are when Liam Neeson is talking to Watto. Watto is the only CG character IMHO that is actually interesting and Liam Neeson talks to him as though he is really on set. I would put those scenes on par with how Mark Hamill acted around the Yoda puppet in TESB and ROTJ.
