For me the first thing that comes to mind is Tales from Earthsea. I don’t think it’s excellent or anything and has plenty of problems but people act like it killed their dog. While it has its problems that have been covered extensively, I think it has a beautiful atmosphere and art.
IMO it would have been better received if it wasn’t advertised as an Earthsea adaptation and was just its own thing.
I enjoyed We’re Back, but it was weirdly dark, and I am positive it wouldn’t age well if I rewatched today.
I’m sure the plot is a mess but I dug what it was going for.
