I agree with you that ROTJ is the weakest of the SE trilogy.
There are so many different opinions on what changes were good and what changes weren't. I personally find the new song at the end of ROTJ very blah. I also don't know how the news of the Emperor's death traveled so fast as to cause dancing in the streets on so many different worlds.
It is because of these changes, good and bad, that I fully support the editing of Star Wars. Since George LUcas was such a pioneer making Star Wars, both times, than I see his blunders as a challenge to the rest of us. It takes some serous work to make it happen, but with all the different versions out there, we can finally have Star Wars just the way that we want it.
Anyways, glad you joined us.
