Re: Has Batman hurt the genre where costumes are concerned?
Here is my take on it; superheroes can wear bright coloured costumes on screen. But it has to be established why. There are plenty of people in real life who wear brightly coloured costumes. Sports players, motorbike riders, performers, etc. They do not look silly because there is a context.
Superheroes wear bright costumes to attract attention, to stand out. To let people know they are there. Let's not forget, a lot of the classic superhero style comes from circus performers in leotards. Strongmen and acrobats performing amazing feats (the Amazing Spider-man, the Incredible Hulk).
There is no Marvel/DC rivalry. Most of the great comic creators worked for both; Jack Kirby, Frank Miller, Grant Morrison, Walt Simonsen, Gil Kane, Steve Ditko, John Byrne, Steve Englehart, Mark Waid...even Stan Lee.
