People who think the original Superman movies were good are muddled by classic rose tinted glasses. They aren't that good in retrospect, including Superman 2. It's simple stage performance, while great, is all it has. The 89 Batman I can still watch, and even with its cheese is still a very enjoyable watch with a very low proclivity for "this is stupid, and the effects are dumb". I'm a huge Superman fanboi, and I still don't have much fondness for any of the original films. Though I do have a special appreciation for red krypyonite (synthetic green krypyonite) Superman getting drunk and flicking peanuts, then getting tossed into a grinder when fighting Clark Kent.
It makes me think people of a certain age, and their appreciation for films from the 70's and 80's without the concept of modern films, like Jaws, which is a great film, but when you go back and watch it today (I literally did a few days ago), the flighty thematic music (outside the thematic duh-duh track), cheesy grim character portrayals, it's very light and not so serious given serious threats. Like much of Spielberg, the fun was the point.
Much of modern DC films lack any significance where fun is concerned, and how they mold that into a serious narrative. So maybe folks of a certain age, myself and the masses included, are seeing that lack of cohesion.
