I've never understood the Ewok hate, actually. They're funny and silly, but in true sci-fi fashion, they have their own society and culture, and they organize to help fight the bad guys. They brought some levity to things.
I'm not sure that it is "hate"--at least, not from me. But the fact that the Battle of Endor did take on a silly, lighthearted tone that made it less serious, and the fact that the Ewoks were a big part of the reason why (but not the only reason--Chewbacca Tarzan yell, I'm looking at you!), takes it down a notch for me. Not enough to ruin the film by any stretch, but definitely enough to put it below Empire instead of at the same level. If you wanna call that "hate," I think you are overstating the point.
EDIT: Same thing with what was added to Jabba's palace. It went from "Jabba is gangsta and is running things, and like any boss, he can have in-house entertainment nonstop" to "let's do a big musical number, Star Wars style!," which I don't think ANYBODY outside of Lucas has ever felt worked well.
Okay fine, it's not true hatred. But time and time again, the Ewoks are pointed out as what brings the movie down. Some people actually do say that the movie is ruined because of them and that whole subplot, and some are more accomodating. Some think they're kinda cool and/or cute but stall the story and thus the movie as a whole. Some think the whole thing is stupid.
Rather than say all that, I used the term "Ewok hate". For once, I tried to be succinct, and look what happened.
Orbert, You'd think they could still make a 5.1 like they do with older albums. Look at what Steven Wilson did with Yes Fragile. I hope they could release that at some point.
Steven is able to craft 5.1 versions of albums because the original multitrack masters still exist, and he can pan any channel to any location. That's why I was saying I don't know how it works with movies. If they went into the vaults, would the original multitrack masters of the soundtracks still exist? I suspect not, because I don't think I've ever seen a film originally released with a 2.0 soundtrack released in 5.1. I've seen (and heard) 5.1 synthesized out of 2.0 via software, but it's usually pretty bad. I always figured that once the soundtrack is finished and married to the film, there's no real reason to keep the masters around.
It may be possible but prohibitively complex and/or expensive, but as far as I know, it's never been done.
