Clark vs. Evil Supes in the junkyard is a great sequence in a mediocre movie though.

This scene is a distillation of what it is about Superman III that I like about it. Clark Kent -- the "mask", the "disguise" -- beats Superman -- the "true identity".

I am very much a fan of the post-Crisis Superman/Clark Kent -- where Clark Kent is who he is, Superman is what he does -- and this is the closest the live-action films have ever come to depicting that version of the character. For that -- and that alone -- I like Superman III.
