I am old! This is a fact proven by the year I was born... 1968. This is also backed up by the fact that I started collecting comic books in 1975. Back then, comics seemed to be just fun entertainment; stories to thrill, scare or just make you giggle. I didn't care how Flash could be hanging out with the Justice League on some far planet, yet still be in Central City fighting Rogues all in the month of June.
I love that we take our hobby serious... but I think over the past 20 years we have began to take them too serious. Super heroes don't follow the same daily planner as we do, have to stop and go the bathroom or worry about bills. That is for us to do and we want the escape from that... and that is what comic books do. Escape!!!
Back in 1977 to 1980, my comic book 'Golden Age' I was reading everything I could get my hands on. Although war comics were my thing, I would venture into the team up books like DC COMICS PRESENTS and THE BRAVE AND THE BOLD and see what was going on in the non World War Two part of the DC Universe. And who cared if Sgt. Rock died at the end of WW2 but was teaming up with Batman thirty years after he died? Not me!
The point is, enjoy the stories for what they are... entertainment. Did you read a comic and feel entertained? Excellent! Now move onto another one and repeat cycle!
