I think it will be shown in theaters, though not widely.
I use IMDB.com for a lot of my movie info. One feature it has is that you can rate a film. This film has been rated by quite a few people who have screened it, and a lot of preliminary user reviews have been written. Here are the applicable links, if you’re interested:

Generally speaking, it appears the Mormons gave it 1’s, the anti-Mormons gave it 10’s, and the thinking public gave it 5’s.
Personally, I’ve found that any movie on IMDB that doesn’t make a rating of 7 is not worth my time to watch. It appears that, solely from the perspective of the art of filmmaking, that audiences are already beginning to reject “September Dawn.”
What I did find interesting were the particularly polarized user reviews. Everything from “This was a POWERFUL cinematic experience!!!” to “One of the worst movies I have ever seen”
Wish I could find the early review I saw again. It was a completely non-biased review that looked at the cinematography, acting, how the movie was adapted from real life accounts, etc etc. Left all the religion out of it.
Basically it came down to it being a really really poor movie that only fanatics on either side would watch, but still probably not enjoy because it was that poorly done.
