The movie is good, but they depart from the truth somewhat to make the story more exciting and dramatic. The book is better, and deals with the social and economic issues in Odessa much moreso than the movie. If you like to read, and you liked the movie, get the book.

Interestingly, the "state final game" against Dallas-Carter wasn't the state final, or played in the Astrodome. It was the semis, played in Austin Memorial Stadium. Carter went on to win the final on the field, but were forced to forfeit due to a massive grade fixing scandal. Also, the game against Permian was 14-9, not the more dramatic 34-28.
