Really good read on the subject:
Now, you must realize, I have been a comic book fan since I was old enough to read. Throughout the eighties and nineties, I endured through the obvious disparity between the rich, utter coolness of the comic books and their embarrassingly campy TV and movie counterparts. Then, finally, after keeping the faith, we came to a window in history where unprecedented interest in comic book material converged with advances in special effects. Finally, superhero movies could be produced that actually did justice to their source material from both a F/X standpoint and a dramatic standpoint.
Thanks, Marcus! Source.
