Superman IV: The Quest For Peace (1987)

This is by far the worst Superman movie that Christopher Reeve ever did. Gene Hackman was and will always be the best Lex Luther, but the addition of that Nuclear Man guy in that awful costume was a bad idea. We all know kryptonite is Superman's weakness, but for a man who is supposed to be more powerful than a locomotive, that measly scratch by 'Nuclear Man' sure did make him look like a wimp. The last fight between Superman and 'Nuclear Man' was hilarious, as Reeve barely touches him and was able to win the fight.
