That political correctnes becomes kind of boring. Who cares what gender or color a superhero is ? Like that is so important. Most of us do not even look as fit. Sooner or later, super heroes should look more fat because that is politically correct, according to some crazy people. If all those demands are acknowledged first and that only afterwards the script is important, i know for sure i will never watch a movie again.
There are enough examples where a great single 3 hour movie(or a 2 part movie) can be made.
For example :
Anita blake is a great series if you are into the supernatural with a non super powered private detective who can do some magic spells. Comics are drawn very nice.
Cloak and Dagger used to be a great series, also in the realm of the supernatural.
If you are into female super heroes, Spiderwoman is great. The original comics are fantasticly drawn.
Blade... Too bad that part 3 was kind of a let down.
Still hoping for Wesley Snipes to return in the character of Blade.
