I sometimes watch the SE’s too.
Why?
For the heck of it. I watched Empire out of curiosity and found it surprisingly watchable. The Laserdiscs and look great (for Laserdisc) and sound absolutely incredible. I also find them interesting from both an historical and technological standpoint.
At least Irvin Kershner gave his blessing for the SE of Empire.
I also find the SE historically significant in its own way. A movie series of such popularity has never been so radically altered before or since. ANH SE long held the record (if it doesn’t still) for the highest-grossing January release in U.S. box office history.
