1. A diverting study in the rolling disaster of adolescence, gathering speed and danger as it goes.
2. The strength of the movie -- which makes sure to show the pressures its characters face, so that all of them are weak but none of them is a villain -- is its recognition of the strength within Meg.
3. It's that central dance between teacher and student that makes the movie both hard to watch and worth your attention -- a subtle waltz of power in which it's difficult to tell who's leading until too late.
4. The story is so well-acted and honestly written that after a while it stops bothering us that we know where it's going.
5. We've seen this unhappy scenario played out many times before, but seldom with a better eye for detail.
6. The film is strengthened by the two leading performances.
7. It's rare that a movie makes a viewer experience the psychodynamics of an encounter so profoundly -- usually theater is a better medium for that -- but Moncrieff has exceptional skills.
8. Certainly no feel-good flick of the summer. But it's always tough and honest.
9. Even with its drawbacks, Blue Car remains an intimate, thoughtful drama, with a performance no one is likely to forget.
10. Has the feel of a novel in which the characters linger in one's memory well after the book has been read.
