Almost every case of movie purists. The Hobbit trilogy was great. The new Star Wars trilogy was great. The old ones are great too.
I have similar issues with music and video games. I almost always love the most hated albums or games in a series based on the loudest commentary online. I also find the most popular entry to be kind of meh. I think average people have boring taste or just follow a crowd or something.
I remember it when I was a kid. I also remember some people gave put more or less candy depending on how good your costume was. Felt incredibly judged in public. Hated Halloween for so many reasons.
