Almost anything I could write here would be redundant given the length of this relationship in pop culture, but just a couple things;
1) People who think disolving the triangle and marrying them was a bad move? Yeah, you're wrong - the triangle was only good at one thing, and that's showing that Lois was smarter than 99.9999999% of the DC population (including Lex Luthor) for even suspecting that Clark was Superman. Otherwise, it's a complete waste of time and an insult to the characters.
2) The stories that show how and why the marriage works? Good stuff, but in short; Clark has 900 different super senses and superspeed, and Lois is still the better reporter, and she genuinely to her core believes in truth and justice, against overwhelming odds. Lois, on the other hand, has never or will never see a man who's more driven to the goal of helping level the playing field between the powerful and the powerless. That's what she sees, beyond the powers is a man who will live (and if need be, die) to set the example for others to follow.
