I was six months old when the first Christopher Reeve "Superman" movie came out.
My introduction to the DCU came from watching reruns of the '60s "Batman" and '70s "Wonder Woman" TV shows in the early '80s. The first two "Superman" movies were also in heavy rotation on HBO at the time. "Super Friends" was also big at the time and I had most of the Kenner Super Power figures to go with that. Wish I had held on to them! When those stations stopped airing the shows I went into such a deep funk (at six!) that my dad bought me my first comic book - "Justice League of America" #182 and that was it. I found a little local book store that had long boxes of back issues and immersed myself in '70s and '80s Pre-Crisis/Bronze Age goodness. "Crisis on Infinite Earths" began shortly thereafter, but my small, seven year-old brain didn't really understand all the stuff that was going on with that, so it took me a while to go back and re-visit that and appreciate it for what it was. I do remember that it took me a long time to adjust and accept the new "Post-Crisis" status quo. I'm sure if the internet had existed back then I would have been a little eight year-old troll! To be honest, to this day, I'm still "stuck" in a Pre-Crisis/Bronze Age world. That will always be the "definitive" era and versions of all the characters for me.
