Haven't seen it yet, but my friend who did said it has a ton of flashbacks, mostly focused on Brigham. Basically showing
how he was prepared. They were surprised how much of the movie did NOT take place during those six days in August, but said it was still good, just weren't expecting that. I really want to see it, even more so now that I know that because I'd love to see more of Brigham's life depicted on film.
