First of all, in response to another message posted, Billings, Montana is NOT a town full of rednecks. I grew up in that town, and I was in high school there in 1993.
I thought the movie was okay. It does have an important message about how people standing together can help defeat bigotry. It shows how "silence implies consent," and that people doing nothing only encourages bigotry. When so many people stood together against bigotry, the incidents stopped, slowly but surely.
The movie does embellish a lot of details, and it leaves many details out. For instance, there is no mention in the movie about the bias incidents happening in the high schools around town about the same time. When the kids saw the adults standing up against the bigotry, many of them started doing that as well, and the number of incidents decreased.
The slogan was actually "NOT IN OUR TOWN" and it was posted on the billboard of a sporting goods store. One would think that the people making the movie would get at least that right.
Some things that happened were very much dramatized, and some things that didn't happen were added. I was a bit confused by the movie the first time I watched it, as so much was changed.
Overall, the movie does have an important message. However, take some time to learn the real story behind the movie.
