The comics I read as a kid were much more influenced by TV and movies. Encountering superheroes as an adult without that kind of childhood sentimentality, it just doesn't allow you, or in my case at least, it wouldn't let me take the characters seriously.
Sentiment: NEGATIVE
I don't think it's a coincidence that comic books appeal so strongly to children. Not that it negates any of their power for adults, but there is something about comics that makes them a perfect storytelling system for children.
As a kid, I loved the whimsical Superman and Batman stuff, and as a teenager, Marvel was more angsty, and that appealed to me. Marvel dealt with more stuff I could relate to as a teenager.
When I started out in the eighties, the idea of creating serious comics for adults was pretty laughable to most folks, and for the longest time it was hard to even explain what alternative comics or graphic novels were. Nobody seemed to understand or care. Not so, any longer.
