Howdy, @TurokSonOfStone1950! 
Glad to see you, man. 
I agree that JLA was a great run. Granted, I’m enormously biased, but which other ongoing of the last 24 years since JLA launched can boast of writers like Grant Morrison, Mark Waid, Joe Kelly, Kurt Busiek, Geoff Johns and others?
In JLA #1, its funny to see where Morrison takes digs at lesser-known characters, be they in-panel or not. Someone will say “What happened to so and so?” with the typical response being “I don’t know, they lost their powers or something.”
Another great aspect of the first arc of JLA is Howard Porter’s art. When I hear his name, my mind instantly flashes to this series. He made a name for himself on this book, one that will hopefully continue to stand the test of time.
