I read the summary before watching and only 1 of the three segments interested me as it was clearly a parody of Coraline.
The episode began with a cgi opening I like the change of style and the fact that Bart was a butter finger was a cool reference to the old ads where Bart was their mascot for a while. However, none of the jokes worked for me.
Then there was some dumb Exorcist parody again not funny the most interesting part for me was that Lenny's voice sounded off I know Harry Shearer threatened to quit but I don't know if he actually did this may have been a replacement voice.
Then the Coraline segment which was the most disappointing. I like how the other world was in a different style it allowed it to be kind of close to a clay look I guess and was a cool way of making the Halloween episode stand out. They have had weird things that stood out since the earliest Halloween specials the devil and Homer Simpson had unique directing, The very first Treehouse of Horror had creative lighting, The Shinning was used to experiment with off- model cartoony facial expressions, etc. Unfortunately, this felt super rushed.
The other one Homer ate himself
It sucked
The most interesting part was that he cut off his finger and there was no blood- the old ones had tonnes of blood.
Yeah so overall no good jokes and some lame stories but some creative animation
