I know how you feel. I was never much into the DC/Marvel comics when I was a kid. That is in part because they were not that widely available in England during the 70s. I maybe had a couple of dozen DC comics (mainly Superman, Batman etc titles). I don't think I had more than a couple of Marvel magazines although Spiderman did find its way into some non-Marvel English comics.I wish I could get interested on this flood of super-hero movies and series that has came around lately. It may be a great source of fun for whose enjoy this kind of stuff. Unfortunately it doesn't make my mind but I already didn't like such themes even when I was a kid. I remember to rather read Disney comics than Marvel/DC!
I mainly bought UK titles such as Lion, Victor and later, 2000AD. Lion & Victor focused mainly on WWII military stories and sports.
In some ways it is a relief not to have been heavily into the DC/Marvel comics as I come to their movies and shows with an open mind. I had no real idea who or what Captain America was supposed to be before the recent movie came out. As for Thor, well I am old enough that my recollection was the alter-ego of a crippled doctor whose walking stick became the hammer. I gather that "origin" has since been re-written.
I enjoy the "superhero" stuff but prefer Sci-Fi. The thing is so much of the "superhero" stuff is sci-fi. Guardians of the Galaxy for example. Or in Legends of Tomorrow, the team fly around in a time/space cruiser. In fact so many of the super heroes in the recent glut of films don't seem to be that super....
Tony Stark/Ironman - not super unless he has his suit on.
Ant Man - likewise
Hawkeye - no super powers just a damn good shot
Black Widow - superb physical condition and training. No super power
Captain America - boarderline position. Granted peak of human ability thanks to chemical treatment
Batman - again, no super powers "just" superb training backed up by a billionaires ability to buy all the tech help he needs (see also Iron Man
Green Arrow - same as for Hawkeye. I gather the new TV show has some super soldier drug enhancements though.
Green Lantern - SciFi. Alien tech lets him do what he does
And so on
