Yes, RotJ is by FAR the worst film in the OT. But thats like saying the worst of the most delicious ice cream flavors ever..or the worst of three of the best movies ever. I dont like using the the word worst when describing any Star Wars movie. Its like saying the worst of your friends.
However...Ewoks suck!
And I love the SE ending to RotJ, that music is so much better than that cornball yub yub song anyday. Seriously, yub yub is supposed to be the end to the Star Wars movie saga...I say no.
My two cents...
