I guess that the complaint that baffles me the most is saying how a new movie ruins the old ones. Each new movie is a new story. The only time that I’ve found it to impact the OT is in the redemption scene in ROTJ and it only made it more powerful for me. But I still get the same feeling from the OT now that I did when there wasn’t even and EU to carry on the story.
I agree, I think new movies can only add, not detract. If a new movie has something I don’t like, it’s easy to ignore when watching the old one.
