You know.... the image in the upper right looks more convincing than any million-dollar cgi effect in superman Returns.

I have to disagree. While many special effects are still very good in the Donner Superman movies some of them do look pretty dated compared to Superman Returns.
I like the shot. What sells it is the intensity of Reeve's face.
Routhe was never allowed to look that intense.
Oh these pictures in the link are excellent! I was referring more to some scenes in the first two movies where the effects do look dated. Some of them, many more, still look great than not but with films where one of them is over 30 years old it is to be expected but they still work real real well.
