such as:
the snowspeeders not being translucent anymore.
the old scene with Biggs at the ending of new hope was an absolutly amazing idea and is now one of my favorite scenes in the SE's
i liked how they cleaned up the smudge under the landspeed in ANH
even the death star scene battle in ANH was much more exciting
the new entrance into cloud city wasnt that bad but as for making all the walkin through cloud city shots have some sort of ship fly by the windows was cheesy and should have been left that plain white... sorda that uneasy feeling
last one i can think of is the bantha heard at the beginning of ROTJ oh ya and the sandcrawler shots in ANH
as for ROTJ... that SE had nothing good in it except for the bantha thing mentioned above... Lucas completely butchered that SE beyond belief!
