On the issue of having too many OT characters in the PT, I agree with you.
I think that Fett's history should have been kept a secret.
I don't feel real strongly about the droids being present either way, but I know that I don't like the way their inclusion was explained (i.e.
C-3P0 being created by Anakin).
Luke and Leia are a given as far as I am concerned.
I would like to see Mon Mothma have some role and I would like to see Tarkin.
I think including Chewie was unnecessary, but I can live with it.
I am still waiting to see Bail Organa.
Absolutely no Greedo!
Jabba was completely unnecessary.
I thought Owen and Beru were a nice touch, even though they weren't given enough lines to be substantial.
Coruscant was nice to see, but I agree that Tantooine was unnecessary. I would still like to Alderaan, although I still think that Naboo should have been Alderaan. I would like to see Dagobah and maybe a mysterious world where Anankin goes in search of the secrets of the force. I really don't want to see the Millenium Falcon, Han, or Lando. I think that it would be too much and bring down the story. Besides, Han is only little older than Luke and Leia, so how come he woudl have a cameo and they would just be born?
I don't think it was necessary to know where Anakin was born. He should have simply been introduced during the Clone Wars.
