Honestly, I really don't see that any different than now.
Only instead of classic films covered in shit, we have pure shit. I don't know about you, but I really like things to act like what they are. I get a cat, I want it to act like a cat. Dumb thing goes and starts acting like a dog, I am tossing it out. The SE is a confusing mess, is it an old film, is it a new film, complete mess.
I don't think a remade sequel trilogy would have any adverse bearings on an eventual restoration of the original trilogy. It would be a bit like euthanasia for the poor old trilogy. Right now the things looks like crap, tubes coming out of every hole, hook up to life support. Nobody even really cares about it anymore. It has worn out its welcome for most people. The poor movies define dead horse beatings. It feels like the decent thing to do, to retire the poor things. Let the sleeping dog die. Burry the bloody horse corps. These movies deserve to be setting on everybodies DVD shelf, not under going cosmetic surgery every few years and having the little good that remains in them squeezed out for a profit.
