Had a thought after my rant, there have been successful TV shows with strong protagonists that happened to be women; Xena, Buffy, Alias. The leads in these could have easily been; Wonder Woman, Spider-girl, or Ms Marvel, but unfortunately it seems the be that some creators think that the superhero genre is so difficult to write/adapt. Look at the running fiasco of some male heroes too, you have producers scrambling to make everything "gritty", then there are creators *coughMarkStevenJohnsoncough* who made R-rates properties into very generic PG-rated movies, hell, one's even on your list of examples.
Look at the successful Comic Movies; they're either extremely faithful (Iron Man, Cap, Blade, Spidey, etc), falls into the creator's realm of expertise/experimentation (Nolan's Bat, First Class, etc), or just caters to the lowest common denominator (X3 the Last Stand, Origins Wolverine, and yes, they were both strangely successful), but there's still a lot of unsuccessful comic book movies, I think they're over thinking it. Alien wasn't amazing because Ridley Scott wrote his Hero as a woman, truth is, he wrote it as a man, then later changed it to a woman. It's the same problem some people have when writing LGBT characters, they're so intent on writing a "Gay Character" when they should be writing a Character who just happens to be gay.
Sorry, rambling. It's just something that's close to my heart, so I tend to get attached to the subject.
