YMMV: The Star Wars Holiday Special
Bizarro Episode: The special is this, mostly, in the larger context of the Star Wars canon. Also to George Lucas and other cast members, who do their best to pretend this never happened.
Misblamed: Some fans blame George Lucas for the quality of this, but in reality he had very little involvement due to filming The Empire Strikes Back at the time. In fact, Lucas had one of his trusted former USC classmates installed as the initial director in order to make sure that the special would be at least somewhat faithful to the original film. Unfortunately, CBS proceeded to fire Lucas' favored director and replace him with the guy that would go on to produce Pee-Wee's Playhouse. The results speak for themselves.
Mondegreen: Jefferson Starship would really like to knoooooooooow if you'll light this guy on fire.
Narm: The whole thing, but special mention must be given to the actor cameos and the attempt at "warmhearted" holiday cheer at the end: Han, Luke, C-3P0 and Chewie are supposed to be moved by Leia's song of hope, but look stoned/bored out of their minds. Considering that Carrie Fisher was whacked off her skull on drugs while making this special, they probably were.
One-Scene Wonder: While the premise was as silly as the rest of it, Bea Arthur's performance as the cantina owner is actually a bit moving. Sadly, it doesn't save the rest of the thing's horribleness.
Same can be said about the animated segment.
Padding: One theory is that the special was originally to be one hour, but the network wanted to sell more advertising, so they insisted that it be expanded to two hours. That would explain some of the more ludicrous scenes.
Squick: Elderly Wookiee Itchy looks like he's masturbating to holographic alien porn, which is completely wrong and disgusting no matter how far away your galaxy is. He's also watching it in the middle of his living room, in front of his daughter-in-law and grandson. Worse yet, this is apparently a common enough occurrence that they don't even bother commenting on it.
Took The Bad Film Seriously: Bea Arthur, alone among all the big-name guest stars. To her credit, she's talented enough to elevate her sequence into something watchable and almost poignant. She was also no stranger to 1970's variety shows, so she knew how to adapt her Deadpan Snarker Mode to the role.
The Woobie: Krelman, Harvey Korman's character in the cantina scene. Yes, he's a bit weird with his head hole, but he's so sincere and so lonely, he evokes sympathy almost accidentally. Cantina barmaid Ackmina and her customers as a whole also fit the bill.
