I try to explain to you. When I was between 4-6 years old, my father introduced me to Superman comics. It was that time where Curt Swan, John Byrne and Dan Juergens drew Superman. Dec 1978 was when Superman the movie came out and my birthyear, so I was just too young to see it on screen, I was just entering the new world. Later my dad rented all the videos from Superman I-IV (fortunately I forgot most of IV). Nevertheless, Chris Reeve was the pure embodiement of Superman I saw in the comics and in the movies. It was like he was breaking the fourth wall and came to life. I believed that a man could fly. It made a profound and deep impression of how Superman should be, he used his brain instead of brawns. He is kind and helpful. He is a hope of overcoming our human shortcomings. That's why this image of Reeve's Superman portrayal made such a long lasting impression into the cultural consciousness of how Superman acts and behaves.
The poster actually looks good - the other photos, not so
Not laziness, but if Synder is all about show and no substance like Watchmen, I would say that the Superman franchise died of greediness after Superman II.
