In most sports movies, you'll have the corny story of triumph and it might be not too great. But this film is different. It uses it's independent edge (it won numerous awards at the Sundance and Caanes film festivals) to not be cornball, but to a good achievement. Michelle Rodriguez definately makes an credible debut as the troubled and always angry Diana, who decides a way to get out some of her aggression is in boxing, and it works, even when she has to face her boyfriend in the (improbable to be sure) ring. Better than I thought, but the liability is that Diana is always angry (so angry that any regular girl's worst day of PMS is Diana's best day) and she does some things to her family and friends that are very questionable, method and emotion wise which almost makes her not the best girl to emmulate. Pretty good, never-the-less. B+
