Random realization:
I have no problem with reinterpreting the look of characters like Dracula, but I have to squash and question an impulse to dislike things like Zendaya being cast for MJ in the more recent Spider-man movies.
I thought about it and I realized that, intuitively, it's all down to copyright. If the original work is still under copyright, I see it as too soon to break from the original creator's conception of the character.
