As for what comicbooks are, most fans know they are more than super powers and what not, but the draw tends to be the fantasy aspect of course...you know, escapism.
The draw is fantasy....sure, comic books are full of fantasy, the simple idea of someone having powers is irrealistic, but so is 70% of science fiction, and it doesn´t make it less serious.
So, the fantasy aspect is not even an issue, as for escapism...no, it´s not.
If you look at escapism as a way forget daily worries, sure, every movie and entertainment is pure escapism; but escapism is usually the fun and wow factor, the "popcorn side of life".
OT of sorts, but that I believe is the biggest gripe many people have with Nolan's Batman; he went overboard with the realism and seriousness angle. Not to say there can't or shouldnt be realsim, but don't go turning the material into something it isn't intended to be.
He didn´t turned he material into something it isn´t intended to be, he, like Ang Lee, made the movie as it should be.
Sure, both have their flaws, but both movies were about the man behind the hero, as it should be.
Brian Singer tried to do the same, with both the X-Men and Superman Returns.
Imagine you, getting powers, how would you deal with it? How would you scope with that new reality?
Why would you take away so many of the very things that make the material popular in the first place?
Dude, i´m sorry to say, but you are still living in the past, in the 60´s and 70´s, where comic book were meant of kids and teens.
At that time yes, comic books were pure escapism, nothing more.....but times have changed, a lot.
If comic books were still that, i wouldn´t look twice at them.
Escapism is inherent to the genre, the same way action and special effects are inherent to it to, but a comic book is not about action and special effects.
