Rather than review and adjust her behavior, the mother subjects all of us to her personal therapy of blaming some "system" (undefined), as if her wrongs are not really her own, that we all do it, and that the "system" requires it.
No doubt over-scheduling and over-expecting occurs, and no doubt it is wrong, and no doubt it has negative consequences for some kids. But nowhere do we learn the extent of any of this. Does it apply to less than 1% of kids? 50%? Most kids? In other words, how big is the problem? And what is "the system?" Peer pressure? Parents? The school board? Colleges? Employers? The kids themselves? We never find out.
As another reviewer has mentioned, we know the point of the movie before we see it, but the interviews (and that's all there is) are repetitive and boring. No insights, no analysis, no new perspectives, no possible solutions. Not even any villains, just "the system."
