I don't know what it is; I grew up a DC kid. LOVED the Neal Adams artwork of those early 70s Batman comics. I loved Green Lantern - Neal Adams, then Mike Grell - and I loved the cross-over titles like Brave and the Bold, and what not. My Marvel was limited to Fantastic Four, though I had anthologies from Spider-man and Dr. Strange.
And in the movies... it's just the opposite. I really got into the Marvel universe, even the characters I didn't care for in the comics (Iron Man) and the only one that sucked was the one I liked the most in print: Fantastic Four. I WANT to like the DC stuff, but they keep f-ing it up. I REALLY liked the Batman v. Superman, but Wonder Woman didn't do much for me. I really like Zachary Levi, but the ads for Shazam! didn't even pique the slightest interest. I suppose I will watch the Snyder JL at some point, but... I don't know. They're missing something for me.
