What really kills it for me is that Wyldstyle has a much more interesting story that is sadly pushed into a corner for the more typical story that we've been told a thousand freaking times. I mean, I look at this Wyldstyle's character and I see a person who really wants to be more than who she is and wants to be taken seriously in a world that only admires her for her looks, but all the film does is reducing her character arc to accepting Emmett as the hero and in the end being his token reward girlfriend.
Even during the last act when it's her turn to be the hero is completely disheartening. Her moment is nothing but a showcase of how awesome she thinks Emmett is by having her say how wrong she was in looking down on him and how everyone should see him as an example at how special they all are. Yeah, this is a character who for the first half of the film is treated as nothing more than an object for guys to ogle over and not pay any attention to, and she's the one who was in the wrong and has to apologize for it. That's her "hero" moment. It doesn't get any better afterwards since her "turn to be the hero" amounts to nothing since the bad guy turns her into the damsel in distress for a second time. Even after she is freed and the battle isn't over, the film decides to kick her while she's down by having her stay behind and telling Emmett "You got this!". It's like the film needed to remind it's audience that she's not the hero.
So yeah. That girl who wanted to be the hero didn't get to be the hero, but at least she got to make the real hero feel good about himself, because that's what everyone should expect from your "strong female characters" these days, isn't it?
