Just One of Life's Little Mysteries

I was just watching Superman and wondering about something that I've pondered from time to time. Why the hell was Clark Kent so taken with Lois Lane? She's probably the most abrasive, obnoxious, and annoying female character ever and yet he seemed so smitten with her. Was this the feminist ideal of the 70s? I remember seeing this movie at the Kadena AFB theatre when it first came out. I thought she was annoying then too and I was probably five years old. Some things I'll just never understand.
