They tie with Superman Animated Series, Lois & Clark for me. But it was a big surprise when I realized that Margo Kidder and Christopher Reeve weren't my mental templates anymore.
Then came 'Superman Returns' and I realized they were my templates for movieverse.
My favourite thing about Lois&Clark, however, is that they made Jimmy watchable.
I'm still sad that I don't know how the series ended. I remember something about a baby and possibly time travel and then nada.
