yeah i'd also like to post more, i don't want to be just a stupid padawan (since i don't 'accept' the PT).
to go back to the topic: i think i found some plot holes (maybe they've been mentionned already but i'm too tired to care now...):
in ANH, when C3PO and R2D2 escape in the pods why don't they destroy them? even if there are no lifeforms they could have done it only to make sure. better to fire needlessly than to be exposed to the wrath of the vader in case it was important.
and also, in ESB, the empire saw that the millenium falcon was heading for bespin because they put a tracker on it. but when leia, lando and chewie escape they don't remove it (as far as I know) so the empire should have found them again after a while.
am going to watch ESB and ROTJ back to back with a fellow SW fan on wednesday, maybe i'll find out more then...
