Wow, so much love for MK here! Usually all we get is how she WASN’T pretty ipso facto the worst Lois.
First, I personally don’t think she was that pretty, but she was definitely the best Lois. She exuded confidence and brass that made her believable as a tough woman, unlike the more recent ones which are all about pretty and low on strength (as usual with modern women...the classic movie era beats out modern for truly tough women, too, despite the seeming paradox).
