that doesn't mean it garantees a good movie like you all seem to be implying.
It doesn't guarantee a good movie, but it does reflect the attitude of the filmmakers toward the source material and the audience, and it's not a bad indicator of whether we're going to get what we paid to see. These stories and characters are popular for a reason, and there are limits to how much you can change them and still honestly call them the same. It's not about the competence of the filmmakers or the quality of the film. It can be good and also respect the source material.
Let's put it in perspective. If, for the sake of realism, you decide to take away everything catlike about Catwoman's costume, and give her a generic movie burglar/commando outfit, why stop there? The one thing left that is silly and unrealistic is Batman himself, running around dressed as a bat in a costume that doesn't look very comfortable or very practical. He seems even more out of place in a movie where everyone else has been stripped of most of their comic book attributes. Why not just dress Batman up in a black jumpsuit with regular body armour, a mess of weapons strapped to him and a simple black spandex cowl over his head? Because he wouldn't be Batman. He might kick serious ass. He might be a great character in a great movie, but he wouldn't be Batman. He would be completely unrecognizable. And if you're a fan of Batman, and Batman is what you want to see, you can't be blamed for being disappointed if somebody takes the liberty of redesigning him in a way that ignores some of the most basic attributes that make him Batman.
I'm not against updating or reinterpreting a great story, but as far as I'm concerned, if the source material isn't good enough to adapt at least somewhat faithfully, then don't use it. If you want to be original, then be original. Make your own movie the way you want to make it. If you want to tell the same story in a different way, then do that and call it what it is. If you are determined to make a straight adaptation, then show some respect for the source material and all of the work that has preceded yours, and keep your creativity within certain established parameters. I don't care if somebody wants to go crazy with a redesign, but if I can't look at an established, even iconic character and figure out who it is without being told, that's too much artistic licence. And that is the case with both the Bane and the Catwoman we've seen.
And I most certainly object to making superhero movies look just like every other action movie. Same with stripping the James Bond franchise of everything that was classy and fun and over-the-top about it. There's nothing left but another generic action movie.
