From all the descriptions and screen grabs I'm probably better off leaving it unseen.
Alright, I have to jump in here and I don't mean this to be humorous.
When I first heard that Lucas had altered and added scenes to Star Wars for the "SE", I knew better than to allow him to put those images in my head. The same for the SEs that followed. I'd seen a few screencaps in magazine articles at the time, so I had an idea of how he'd jacked it up.
I made a matter-of-fact decision not to allow Lucas to gaslight me. In my world, Star Wars - as it has existed since I first saw it in 1977 - is completely unchanged.
I saw the Holiday Special when it aired. It's shockingly bad. I mean actual head-shaking, eye-rubbing, "who the FUCK thought this was a good idea?!!!" bad. As someone has already mentioned, not "so bad it's good" - just cringe inducing on every level.
Do yourself a favor, man. Pass on the thing. In the truest sense of the phrase - you aren't missing anything.
