I have been a Superman fan for as long as I can remember. When I was a kid, I would throw on my blue pajamas with my red underoos on the outside and run around the neighborhood with a red towel as my cape.
Strangely enough, I was not a huge fan of the first Superman movie when I first saw it because it was the bloated extended cut they put on television as a two night event. I remember being so bored waiting for Superman to show up, but, when he did, I was utterly hooked. That helicopter sequence with Lois still works on me at such a primal level that only the trench run from the original Star Wars can match.
A short time later, I watched the old 1940s cartoons and they were like a bolt of lightning compared to the utter garbage that passed for animation during the 1970s and 80s. This was Superman unbound. There are a few moments from the 90s cartoon that come close to tapping into what made those early shorts great, but they were too few, unfortunately.
Likewise, the comics were rarely able to recapture that feeling for me, but the ones that nailed Superman, really crystallized my love of the character. John Byrne's Man of Steel #2, Morrison's JLA, All Star Superman, and Final Crisis are all timers in my book. And now, Superman Smashes The Klan has joined them.
What about you guys? What are the moments and stories that made you a Superman fan for life?
