The thing that bothers me is that it seems to be presented as: even though she's really smart, she's a loser until she succeeds at skating.

Maybe in the movie she is brilliant but doing what everyone expects her to instead of what she loves, but that doesn't come across in the previews. They make it seem like she sudeenly decides she'll be a skater 'cause being brilliant just isn't cool enough. That's the assumption that pisses me off.
