Good point. The movies in the last 20 years have tried really hard to be too philosophical at the expense of good and more heartfelt stories about him. The have shown a Superman character that feels too alienated from the human race. He is not nearly as charming and charismatic like he used to be in the Reeve movies.
Look at Diana in the Wonder Woman movie, for instance. She was very likable during most of the movie. She was friendly with everybody and let people get close to her. And she was eager to help. It didn't seem like a burden. Same with Aquaman. No wonder people really liked them..
