Well Superman had all kinds of strange, additional powers in the comics at the time, so the "amnesia kiss" didn't really stand out or bother me all that much. Plus the Donner movies always had a slightly magical tone to them anyway.
I just wish they had included the Superman and Lois conversation that we see in the Donner cut before
that scene. It was not only beautifully written, but made Lois's emotional breakdown MUCH more believable and understandable.
And yes, I'm just gonna say it-- I love the cellophane S he rips off his chest as well. Thought that scene was cool as hell when I was a kid, and I STILL think it's cool. So there.
