Imagine being a kid in 1978 and waiting very impatiently for the sequel to Star Wars to be released. Characters from the film have been everywhere, from Mark Hamill hosting the Muppet Show (excellent, I mean, Darth Gonzo rules) to Darth Vader showing up on two different Saturday morning preview shows the same night. For younger viewers, those were specials the networks aired so you would know which cartoons to avoid the following Saturday morning. There really was nothing like this phenomenon that had been seen since the Beatles.
So I imagine that everyone involved really wanted to get some more visual product out there, to keep the brand fresh in peoples' minds. When it was announced all of the fans thought we'd get a quality product, certainly George Lucas wouldn't let his universe be sullied by inferior ideas and writing, right?
Most of the positive comments that can be mustered come from the cartoon that introduces everyone's favorite worm food, Boba Fett, who is rather useless in the poorly drawn segment. He does look the best out of Han, Chewie, Luke and C3PO, but that's damning with faint praise.
It all points to the awfulness the final four films would be, if we had only known. I'd be surprised if Disney doesn't eventually release this thing to the public, since it seems most people will buy anything with Star Wars on it these days, and multiple times.
I'm not going to say this is the worst thing I've ever sat through (it's not) but the sheer disappointment of it makes me never want to view more than 4-9 minutes of it again. And I can sit through both Challenge of the Super-heroes and Roast of the Super-heroes.
