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.
My general personal rule is “If I’m entertained then it’s good” hmrm I don’t care what anybody says.
Obviously nothing wrong with that but I personally think it’s important to distinguish between “It’s good because it’s a bunch of moving pixels and it’s not terrible, and I’m lazy and have nothing else to do” and “it’s so good I thought about it for weeks after watching it”
I would call the first example mediocre at best even if I technically enjoyed watching it that time.
