In short, the comic industry doesn't want female-led movies for the same reason Nintendo doesn't want any movies of their works: "We tried a little before and it sucked, so we're not gonna try anymore".
So walk me through the logic, here…
1. Under-budget and under-sell female superhero movies because you don’t believe in them
2. Cast eye-candy “talent” in the lead role who can barely act their way out of a paper bag
3. Have a script that should have stayed in the garbage
4. Use the resultant poor box office to justify never making another female superhero movie
Way to go, fellas. Justify the fuck out of that self-fulfilling prophecy.
