It's a bit of a backhanded message if Hollywood caters to anime fans by giving them subpar movies. Hollywood throws all this money around, but nothing good really comes out of it. If anything, they end up just disappointing old fans and turning away new fans instead. They don't do a really good job of recognizing the fans and what they want.
What's more, this "recognition" by Hollywood isn't some societal acceptance. It's just part of their opportunistic mindset of grabbing money wherever they can. Hollywood knows that they can get money from anime fans, so they toss out a half-baked movie to rake in quick sales. That's all there is to these adaptations.
