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.
Hehe yeah, a little worried about watching rock-a-doodle now as an adult, it was great when I was a kid. We knew enough french to get the name pun (chant eclair = sing clearly) at the time and I guess that helped it feel a little more special for us. Not sure if the movie would still hold up from what I remember of it.
