Disenchantment had a good story that was marred by bad writers. Ironically, the most interesting and sympathetic characters were the ones we got to see the least of [the second wife, Oona, and her half-amphibian son]. They couldn’t figure out what to do with the mains, so we end up with Elf Fry and demon-cat Bender hanging out around a character who is intentionally unlikable. Those characters can work really well, but they have to be juxtaposed against solid, good, likable characters or at least surrounded by a tone that makes them sympathetic. Disenchantment doesn’t really acquire this tone until the final episodes, at which point many viewers have already given up on the show.
For me, the best part was the relationship between the king and his second wife and political entanglement it was borne out of and led to questions about what really happened to the first wife. (spoilers) I was happy that Oona WASN’T the secret villain in the season-one twist and the imprisonment of the innocent if slightly degenerate half-amphibian son of Oona and the king when succession became called into question with the return of Queen Dagmar was a genuinely moving moment.
A big problem that it had was that it had a good story but was not good at developing characters. So, even though it was a really short series, the early/middle episodes that tried to develop the characters but didn’t advance the story were the worst.
They waited too long, I think, to make clear that the king was a more nuanced and complex character than he presents himself as throughout much of the show. People are right that it gets good at the end, but you need to, uh… make the rest of the show good, too.
The second half is better than the first half, picking up with episode 6. Episode 7 lampshades how awful all of the characters are when the one-eyed giantess literally comes out and says that every one of the mains are horrible people.
It was better than whenever Futurama tried to tackle D&D, but it struck me as going for [from what little I know about it and what little I’ve read] a Cerebus vibe–snarky, mean fantasy comedy that leaves a door open to go “dark” and “serious” when it wants to. It didn’t do a great job, but it was just good enough that I wish it was better.
