Almost as cool as a shark riding on the back of an elephant, trampling and eating everything in their path.
I suspect the effects of both Superman and Superman II were more impressive at the time than those of Superman Returns will be today.
Effects have gotten to the point where most people only notice/speak about them if they're crap. Which happens a lot unfortunately. The last three Star Wars movies had some pretty spectacular effects, but were also riddled with a lot of craptastic garbage to complain about. I don't remember anyone complaining about the effects of the time when the first three movies premiered.
