I don't think I could get a friend to sit down to see the chronological order - I don't know if I would sit through the Prequels again. Cinematic order is much better, cause I can enjoy the OT and then mention without a drop of enthusiasm, "Oh, yea... there are Prequels... you know, if you want to see those, too."
As far as the Clone Wars and Ewok Adventures go... I think I'll spare my friends.
