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.
Anything fourth wave Marvel, people were done after infinity wars and just shit on anything since because it’s too much nerddom on their systems. I still loved she-hulk but people didn’t.
