When I hear the Simpson and Futurama creator was making a new show, I was really excited; however Disenchantment turned out to be just ok.
It's fine for a one time watch and that's kind of sad, because the other two shows are great and fun to rewatch. Some jokes are funny, but a lot of them are mediocre.
One big change with Disenchantment is that it has an overarching plot, unlike the Simpson and Futurama (I know there are some plot driven episodes here and there, but they aren't the main focus of the show). There is nothing wrong with that, in fact I think thats one of the main reason I keep coming back to the show to see what happens next.
